This information should assist students who have not yet selected a faculty mentor.
Division of Rheumatology, Allergy and Clinical Immunology
School of Medicine, University of California at Davis
Our laboratory studies the interface between the skeletal and immune systems, a newly emerging area of research called “osteoimmunology”. Haematopoietic stem cells in the bone marrow give rise to both T cells which are important in inflammation and osteoclasts that regulate bone resorption. Differentiation and activation of osteoclasts from their precursors is tightly regulated by cytokines and growth factors such as receptor activator of nuclear factor kappa beta (RANKL), tumor necrosis factor (TNF) and various interleukins. Receptor engagement of these molecules results in signaling cascades and transcriptional changes that give rise to medical conditions such as rheumatoid arthritis, osteoporosis and osteopetrosis. Using in vivo gene transfer of immune cytokines IL-23 and IL-17, we have established new arthritis animal models that highlight the importance of these immune cytokines in arthritis initiation and bone homeostasis. Using in vitro assays, we continue our attempts to define the cellular and molecular mechanisms that take place in this fascinating interplay of the immune and skeletal systems.

CBS: Neuro, Physio & Behavior
Cranial (or anterior) cruciate ligament (CCL) rupture is one of the most common orthopedic conditions in dogs. CCL rupture results in instability within the stifle that initiates a downward spiral of synovitis, articular cartilage degeneration, and eventually osteoarthritis. Currently, intracapsular techniques replace the ruptured CCL with an autologous tissue or synthetic graft. However, these grafts aren't strong enough and so the repair is usually augmented with some form of extracapsular reconstruction. We have developed a viable alternative that should be strong enough on its own to return joint stability. Our unique method uses stem cells to engineer a ligament in vitro. Our current research is finalizing the optimal growth factor cocktail and mechanical intervention before beginning our implantation trails.

Canine and Equine Genetics
Department of Population Health and Reproduction
Our current and future research plans are directed towards elucidating the molecular basis of inherited diseases in companion animals. We are interested in developing tests to help breeders eliminate inherited diseases in dogs and horses. A large number of the diseases seen in veterinary practice that affect purebred animals have a heritable basis.
Characterizing inherited disease in dogs has the added benefit of providing an animal model for human diseases. Presently we have projects in both horses and dogs. We are working on the molecular basis of chronic progressive lymphedema in horses and susceptibility to pneumonia in horses. In dogs we are working on the molecular basis of Addison’s disease, cleft palate, Intervertebral disc disease, myopia, vertebral spinal malformations and longevity. My laboratory has identified the mutations responsible for lethal white foal syndrome (LWFS), HERDA, and Hoof wall separation syndrome (HWSS) in horses and hyperuricosuria (HUU), spinal disraphism (SD), Juvenile Addison’s disease (JADD), Alaskan Husky encephalopathy, Saluki encephalopathy, chondrodystrophy, glioma susceptibility, cleft lip, palate and syndactyly (CLPS) and cleft palate (CP1).
I welcome STAR students interested in genetic diseases.

SOM: Medical Microbiology and Immunology
I am a microbiologist interested in Salmonella pathogenesis and host response. Our group has pioneered the use of a calf model to study Salmonella gastroenteritis and a rhesus macaque model to study co-infections with non-typhoidal Salmonella and HIV. In addition, we use the advantages of the mouse model to study host and bacterial factors involved in orchestrating intestinal inflammation. On the host side, we are interested in pattern recognition by the innate immune system (TLRs, NLRs and complement), pathways that amplify responses in tissue (the IL-23/IL-17 axis and the IL-18/IFNg axis) and effector responses induced in the intestinal epithelium (defensins, lipocalin-2, calprotectin, iNOS etc.). On the bacterial end, we study mechanisms that enable typhoidal Salmonella to evade innate immune recognition and mechanisms that enable non-typhoidal Salmonella to take advantage of the host inflammatory response to out-compete the microbiota in the gut.

Department of Microbiology and Immunology, School of Medicine
Our laboratory is interested in innate immunity of mucosal tissues, and we are focused on key effector molecules of host defense: antimicrobial peptides. Antimicrobial peptides are endogenous antibiotics, isolated from diverse species throughout the plant and animal kingdoms. They represent an evolutionary ancient mechanism of host defense. These peptides typically have a broad-spectrum of antimicrobial activity that includes bacteria, fungi and certain viruses. Defensins are the major class of antimicrobial peptides in humans and other mammals. Investigations from our laboratory have discovered that certain defensins are expressed in abundance by epithelial cells at wet mucosal surface. Our studies support a model - antimicrobial peptide constitutes part of an active, early host defense response of challenged epithelial cells. The long-range goal of our research is to understand the specific role that these epithelial antimicrobial peptides play in mucosal innate immunity, including maintaining homeostasis at baseline and responding to challenge by pathogenic microbes. Our current collaborative studies include: (i) characterizing the primary structure and biological activity of the tissue forms defensins, (ii) defining the key regulatory steps for the expression of these molecules, (iii) exploring potential mechanisms of therapeutic modulation of these systems. The investigations include biochemical and molecular biological approaches and analysis of transgenic and other animal models.

The p53 family proteins are transcription factors and consist of p53, p63, and p73. Each member regulates a diverse array of both common and unique target genes. These target genes mediate various activities for the p53 family proteins, including the cell cycle control, apoptosis, differentiation, senescence, DNA repair, normal development and tumor suppression. p53 is a tumor suppressor and found to be mutated or inactivated in greater than 60% of all human cancers. Mutant p53 is not only defective in tumor suppression but also promotes tumor formation. However, p63 and p73 appear to be necessary for the development of various tissues and immune response. To address these diverse activities for the p53 family proteins, we focus on the following areas of research: (1) to identify both common and unique target genes for each p53 family member and their functions in tumor suppression and development; (2) to determine the mechanism by which the p53 family proteins differentially regulate gene expression; (3) to determine the mechanism by which mutant p53 obtains a gain of function in promoting tumor formation; and (4) to determine the mechanism by which the expression and activity for each p53 family protein is regulated.
Potential Projects for STAR Students:
The p53 pathway, including p53, p63, p73, Mdm2 and MdmX, in dog osteosarcoma, sarcomas, histocytic sarcomas, and melanoma

Musculoskeletal adaptation, post-traumatic osteoarthritis, bone, biomechanics
UCDMC Department of Orthopaedic Surgery
Dr. Christiansen is a faculty member in the Department of Orthopaedic Surgery and the Biomedical Engineering Graduate Group. His research investigates the adaptation of musculoskeletal tissues, particularly bone and articular cartilage, to the mechanical environment, injury, aging, or disease using small animal models. The musculoskeletal system has an innate ability to repair and optimize itself based on the mechanical demands placed on it. By studying this adaptation, we are able to uncover the underlying mechanisms that contribute to diseases such as osteoporosis and osteoarthritis. Musculoskeletal adaptation is quantified in these models using advanced imaging techniques, histology, and mechanical testing. Current projects in the Christiansen lab include investigation of biomechanical and biological mechanisms contributing to the development of post-traumatic osteoarthritis, investigation of systemic bone loss following bone fracture or other musculoskeletal injury, and determining the effect of peripheral sensory nerve function on bone metabolism and bone adaptation to the mechanical environment.

Department of Pathology, Microbiology and Immunology
Dr. Coffey studies the ecology, evolution, and transmission dynamics of mosquito-borne viruses including chikungunya, Zika, West Nile, and St. Louis encephalitis that are significant causes of human disease with no licensed human vaccines or treatments beyond supportive care. The goal of her research is to understand patterns of viral molecular evolution and the viral genetic factors that promote arbovirus emergence and severe disease. Her work focuses on how intrahost viral genetic diversity generated by error-prone viral replication influences infectivity and transmissibility between mosquitoes and people or animals. She and her team also developing cheap and convenient improvements to surveillance in mosquitoes by detecting viral RNA in saliva expectorated by sugar-feeding West Nile virus vectors in California. They are also developing approaches to increase safety of candidate live-attenuated chikungunya virus vaccines by restricting their potential to develop revertant mutations that cause illness in vaccinees. Together with the California National Primate Research Center, the team is developing a non-human primate model of human Zika virus in pregnancy that is being used to define the roles of Zika virus mutations in fetal disease and for pre-clinical testing of therapies and vaccines.

Neuroimmunology, sexual dimorphisms, blood-brain barrier
VM: Anatomy, Physiology & Cell Biology
My research focuses at the neuroimmune interactions at the blood-brain barrier (BBB) and its role in the neuropathogenesis of neurodegenerative disorders, like Multiple Sclerosis (MS). MS is the second leading cause of neurologic deficits in young adults and exhibits a high sex-bias affecting three times more women than men. MS is characterized by the pathologic trafficking of autoreactive-leukocytes into the central nervous system (CNS). We are interested in 1) assessing the contribution of IL-20 cytokine family signaling and 2) the role of sexual dimorphisms at the BBB using the murine MS model Experimental Autoimmune Encephalomyelitis (EAE). Likewise, we want to 3) assert if Canine Immune-Mediated Encephalitis (CIME) could be characterized as a natural MS model. CIME etiology is elusive but, but there is evidence to suggest that is due to autoimmunity. Lastly, we are in the developing a model 4) to assess changes in brain microvasculature as a result to pesticide exposure using zebrafish. This model will lead to better understanding of the role that environmental factors may play in of BBB disruption and consequently on neurological and neurodevelopmental disorders.

Possible 10-week research projects:
Investigation of tick vectors in areas where Babesia conradae is endemic
-this project will focus on the epidemiology of B. conradae, a protozoal parasite of domestic and wild canids. Tick vectors have been identified most of the Babesia species affecting humans and small animals, however, a competent tick vector for B. conradae has not been identified. The aim of this project would be to trap and identify both soft and hard ticks in areas of California where B. conradae has been diagnosed. Additionally, the project will aim to identify tick species found on trapped coyotes and work to determine whether they harbor known pathogens of domestic dogs.
Validation of a point-of-care assay for disseminated, invasive aspergillosis
-Aspergillosis can be an invasive fungal disease of dogs and is generally associated with a grave prognosis. At present, diagnosis can be made by either identification of the organism via cytology or histopathology (which requires expertise and/or invasive techniques) or urine or serum tests which must be sent out for interpretation. In this project, a student would work to validate a point-of-care Aspergillus antigen test kit, comparing results to the current gold standard.

The two main areas of interest are neural proliferation and synaptic differentiation in rodent model systems. The Diaz lab uses genomic approaches such as DNA microarrays to identify genes differentially regulated in nervous system development. Individual candidates genes are studied with molecular and cellular techniques including primary neuronal culture, immunocytochemistry, electrophysiology, and transgenic mouse models. Potential projects include: 1) understanding the role of transcription factors during neural proliferation in the cerebellum and potential implications for diseases such as brain tumors; 2) dissecting the role of a novel family of transmembrane proteins in synapse development and potential implications for neurological diseases such as mental retardation and schizophrenia.

Department of Radiation Oncology
Dr. Dieterich’s expertise is in the area of medical physics, specifically stereotactic radiosurgery, small field dosimetry and respiratory motion management.
My Research interest: On the human side of Radiation Oncology, I have been working in the field of stereotactic radiosurgery (SRS) for over a decade. SRS delivers very high doses of radiation with submillimeter precision to tumors; early results in local control far exceed traditional radiation regimens. While this treatment modality for cancer has gone from novel phase I trials to general clinical acceptance during this time, much is still unknown concerning the radiation biology and the treatment uncertainty. I believe much can be learned from studying naturally occuring cancers in companion animals vs. the xenografted mouse models typically used in radiation research

Dr. Eckmann investigates the cellular and molecular pathogenesis of infections with enteric pathogens and the mechanisms underlying the regulation of intestinal inflammation. His studies employ animal models of intestinal infection and inflammation and apply molecular, microbiological and histological approaches to elucidate the key genes and cellular and molecular mechanisms that govern intestinal host defenses against enteric pathogens and regulate inflammatory responses in the gastrointestinal tract. Current studies define host defense mechanisms against the protozoan pathogen Giardia and the bacterial pathogens Escherichia coli and Salmonella.

My research focuses on omnivore nutrition, in particular dogs and cats. I enjoy evaluating problems on both a clinical and basic level, and many of our findings are immediately applicable to the nutritional management of dogs and cats. My current research interests are trace mineral and amino acid metabolism, obesity, carnivore nutrition, nutritional idiosyncrasies of the cat, improvement of pet foods and clinical nutrition. I am the Scientific Director of both Feline Research Laboratories and the Amino Acid Laboratory.
Through the Amino Acid Laboratory, we have analyzed thousands of whole blood and plasma samples from dogs eating grain-free diets suspected of developing dilated cardiomyopathy. Detractors of this condition claim that it is a breed related problem, and in some breeds that may be the case. That said, we saw numerous mixed breed dogs with this condition. The other observation from our laboratory was that there was a preponderance of dogs eating grain-free diets developing cystine stones. This investigator believes the sudden increase in cystine stones may be caused by the grain-free diets. Once awareness of the association of taurine deficiency and grain-free diets was on the rise, I suspected that companies were increasing the amount of methionine and cystine in their foods, resulting in higher rates of cystine loss in the urine and the development of cystine stones. We propose to review the thousands of data points we have collected and test the hypotheses regarding the relationship of grain-free diets and breed of dog, as well as the occurrence of cystine stones in dogs eating grain-free diets. Note that students will not only get experience in working with data in a retrospective format, but also will have the opportunity to work in the Amino Acid Laboratory under the direction of our lead technician.

Center for Vectorborne Diseases
Summer veterinary students have several opportunities from which they can choose a summer project. The emphasis in the laboratory is disease ecology, epidemiology, and theory of infectious diseases, primarily in vector-host-pathogen systems although there are several non-vector transmitted diseases being studied as well. Students should expect to work every day all day, learn laboratory and/or field skills appropriate to their interests and project, and meet with Dr. Foley as early as possible (preferably in the spring) to confirm a project. Skills will be acquired through work with other students, technicians, and faculty in the laboratory; once a veterinary student is comfortable, they may expect to spend much of the rest of the summer obtaining data relevant to their project, analyzing the data with faculty supervision, and hopefully prepare it for publication.
Dr. Foley can be reached at firstname.lastname@example.org.
Dr. Gagneux is interested in primate molecular diversity. His lab investigates the evolutionary mechanisms responsible for the generation and maintenance of primate diversity, its potential roles in protecting populations from pathogens as well as potential consequences for reproductive compatibility. He is currently studying cell-surface molecules of sperm cells in closely related primate species. His focus is on glycans, the oligosaccharides attached to glycolipids and glycoproteins of the cell surface. The numerous parallels between the surface molecules of successful pathogens and those found on the surface of mammalian sperm, invite the analogy between internal fertilization and “extremely successful infection”. These interests examine the differences in sperm surface molecules and sexual selection (via sperm competition and cryptic female choice) and whether such differences might contribute to reproductive incompatibility and speciation due to female immune rejection of sperm with incompatible glycoconjugates. Dr. Gagneux has studied the behavioral ecology of wild chimpanzees in the Taï Forest, Ivory Coast, population genetics of West African chimpanzees, and differences in sialic acid biology between humans and great apes with special consideration of their differing pathogen regimes. His great concern is that the current surge in interest for comparative genomics is not being translated into direct support for the conservation of primates in their endangered natural habitats.

Dr. Gareau is a physiologist primarily interested in studying the microbiota-gut-brain axis. It is increasingly being recognized that the microbes that live the gastrointestinal tract, collectively referred to as the intestinal microbiota, can contribute to modulating cognition and mood. The research focus of her laboratory is in determining how manipulating the microbiota within the gut, using models of infection with bacterial pathogens or administration of beneficial probiotic bacteria, can change cognitive function, anxiety, and depression-like behaviors in mouse models of disease. Dr. Gareau has a particular interest in how the microbiota-gut-brain axis responds to stimulation with psychological stressors and under conditions of intestinal inflammation, such as in models of inflammatory bowel disease (IBD). Ongoing projects in the laboratory include studying behavior in mouse models of IBD and following pathogenic E. coli infection.

Microbiology, molecular biology, host-pathogen interactions, blood-brain barrier, fungal pathogens
Dept. of Pharmacology, SOM
Over the past few years our research has focused on understanding how some pathogens are inherently capable of entering the brain, always with the underlying notion that these mechanismsmight be exploited for the development of drug-delivery systems across the blood-brain barrier for the treatment of brain disorders. My research has focused on the human fungal pathogen Cryptococcus neoformans - the leading cause of a life-threatening fungal meningoencephalitis. Approximately 625,000 people die from this infection each year around the globe mostly due to the difficulties associated with destroying the pathogen once it gets into the brain. Most patients succumb to the infection because of increased intracranial pressure and lack of adequate fungicidal drug regime. Not only does this organism represent a medically relevant pathogen with fascinating mechanisms of pathogenesis but also it serves as an excellent model system for studying other fungal pathogens with central nervous system involvement. We use a multidisciplinary approach that includes proteomics and RNA-sequencing to examine the physical and molecular changes in the brain endothelium and to identify gene products in C. neoformans that elicit these changes during attachment to- and migration across the blood-brain barrier.

My research focuses upon the skeletal system, its development, and the mechanisms whereby it adapts to changes in the local microenvironment.
The skeleton responds to changes in applied loads. Under conditions of reduced use (as occurs during spaceflight or prolonged bed rest), bone is resorbed; when excess loads are applied, more bone is made, to reduce the stress placed upon them. Osteoblasts, the bone-forming cells, are responsive to a variety of stimuli, and we have begun to characterize the downstream signaling events involved in the conversion of an external load into a bone-forming response. This process is termed mechanotransduction. Current areas of research include purinergic signaling and epigenetic regulation in response to in vitro loading.
I also examine how pericellular oxygen tension affects bone cells bone turnover, and bone repair. The oxygen tension within bone can vary under certain circumstances; for example, fracture and limb unloading promotes hypoxia in osteocytes. In collaboration with a colleague at Lawrence Livermore National Laboratory, we are examining the influence of altered oxygen tension perception upon Wnt and BMP signaling in mice.
Additionally, we study how aberrant bone formation can cause pathologic conditions, such as vascular calcification.

Our lab studies wound repair and tissue regeneration. We use cell models (skin cell migration studies), ex vivo tissue models (wound healing in a piece of human skin in a petrie dish), animal models (wounds in mouse skin) and we also carry out translational research where we apply what we have learned at the bench to our clinic patients (Dr. Isseroff is also chief of dermatology at the VA hospital and directs the wound clinic there, where patients with diabetic non-healing wounds, and other wounds are treated). In addition, we have just established a pig wound model, that the FDA prefers for testing all new wound therapies. We plan on generating an impaired healing pig wound model, by using pigs that are diabetic, or by infecting the wound surface with pathogenic bacteria. In addition to the PI (Isseroff), our lab is staffed by MD and PhD postdocs, three PhD graduated students, junior specialists, a senior scientist. We interact closely with the Stem Cell program and we are funded to create a wound healing bioengineered tissue construct that is seeded with mesenchymal stem cells. We also study the effects of chronic stress on healing, and how it alters the immune response that impacts on healing. We offer bench or clinical (human patient) projects.

"My research falls in the realm of companion animal epidemiology: the study of causes of health and disease in populations of dogs and cats. The studies that I do are non-experimental (or observational), and generally (but not always) do not involve in handling animals and do not involve laboratory work. Examples of STAR projects that I have been involved with in the past include studying factors affecting survival in dogs and cats that underwent cardiopulmonary resuscitation, factors affecting survival in dogs with peripheral nerve sheath tumors, predisposing factors to secondary glaucoma in dogs, determinants of patient outcome in cases of aortic thromboembolism, prognostic factors for recovery of function following intervertebral disk protrusion in Dachshunds, and evaluation of national trends in the submission of biopsies of suspected vaccine-associated sarcomas. These kinds of studies often begin with ideas formulated by students, and we figure out a way to study them in the time allotted for the STAR program. I am currently trying to obtain funding to conduct epidemiologic studies into novel statistical approaches to studying possible adverse effects of vaccination on chronic diseases in companion animals."

Tissue engineering, bone, biomaterials
Research in the Leach laboratory is primarily in the broad area of TISSUE ENGINEERING. Within our research program, we seek to engineer functional replacement and temporary bridge tissues while also developing model systems to study physiological and pathophysiological tissue formation. We initially develop many of our projects with an eye toward bone tissue engineering, and these findings are subsequently applied to other areas of tissue repair including cartilage and cardiovascular engineering, as well as wound healing.
All projects in the lab are linked by the hypothesis that combinatorial approaches to tissue formation are superior to individual stimulation. More specifically, successful tissue engineering approaches will be realized upon the proper spatial and temporal presentation of cells, signaling molecules, biomaterials, and mechanical stimulation.

Current research includes mass-tagged enabled multiplexed immunohistochemistry, and novel slide-free microscopy.
How microscopes work in actual clinical pathology has not changed materially in well over a century. Microscopy with Ultraviolet Surface Excitation. MUSE is a novel approach for obtaining high-resolution, diagnostic-quality histological images from unsectioned thick tissue specimens, avoiding the need to perform extensive tissue processing and thin physical sectioning. MUSE is notable for its optical and mechanical simplicity. Micron-deep images of the specimen surface are generated with 280-nm UV excitation provided by off-axis light-emitting diodes (LEDs). Excitation with such short-wavelength UV light excites a wide range of exogenous dyes, and the resulting visible-band fluorescence images can be captured using ordinary microscopic optics and standard CMOS or CCD cameras. These multicolor fluorescence images have novel contrast but can also be converted to resemble conventional hematoxylin- and eosin-staining. A sample can be prepared for MUSE in around a minute. Extended fields of view can be captured from whole organs with microscopic detail. This non-destructive process leaves the sample intact for subsequent downstream molecular or genetic analysis. In addition, images can include shading and depth cues that reveal surface profiles important in understanding the three-dimensional organization of complex specimens. This inexpensive, rapid, and slide-free, sample-sparing method has potential to replace frozen sections, and may have other applications in both high- and low-resource settings.
EXAMPLES OF POSSIBLE PROJECTS:
1. Survey a suite of familiar and unfamiliar fluorescent stains to learn what work best for either recapitulating standard hematoxylin-and-eosin stain appearance, or for staining new tissue components that are not easily detected just with H&E, like collagen, elastin, amyloid, PAS, etc.
2. One of the things we have not yet been quite successful with is getting immunofluorescence to work with MUSE. The problem may be inadequate excitation light power (so we would need different sources), or alternatively, we need brighter labels. There are ways of approaching both these things, but this may be a more difficult project without guarantee of success. Still, it’s very important, and a lot would be learned along the way.
3. Application to vet path cases would be very relevant, as MUSE can both provide intra-operative guidance, as well as point-of-care histology in veterinarian offices, which could be very helpful in decreasing the need for return visits and accelerating care.

Department of Neurology, SOM, UC Davis
Liu’s research leverages cancer elements (oncogene/kinase Src, tumor suppressor miR-122/125b) to develop new drugs for treatment of neurological disorders. Liu and colleagues developed a new concept “aberrant cell cycle diseases” that reveals cancers and neurological disorders share common mechanism of aberrant cell cycle re-entry (http://downloads.hindawi.com/journals/tswj/2012/491737.pdf).
In this concept, oncogenes/kinases (e.g., Src, ERK, CDK, others) promote cell division in cancers, but the same genes drive neuron to re-enter the cell cycle which results in neuronal death in neurological disorders. Liu further enriched this concept with evidence that oncogenes/kinases promote cancer cells crossing from blood into tissue to cause metastasis in cancers, whereas the same genes mediate cell infiltration and blood brain barrier (BBB) disruption in neurological disorders. Therefore, numerous approaches that treat cancers can be repurposed to treat neurological disorders, as these two diseases share common mechanism.
These ideas are strongly supported by the pharmacological data that show oncogene/kinase inhibitors can not only treat cancers, but also treat neurological disorders. For example, several labs in the UCD Cancer Center reported that Src inhibitor PP2 blocks metastasis and kills cancer cells; while Liu and colleagues showed PP2 promotes neuronal survival and improves BBB integrity after stroke an traumatic brain injury (TBI). Based on these concept & ideas, Liu established his research program that consists of four ongoing projects:
Project 1: Inhibiting oncogene/kinase Src for treatment of TBI. This project studies Src mechanism of TBI.
Project 2: Elevating tumor suppressor miR-122/125b for treatment of stroke and TBI. This project explores new generation microRNA drugs to treat neurological disorders, such as stroke and TBI.
Project 3: Developing microRNA drugs for SARS-CoV-2/Covid-19 associated brain injury in collaboration with local UCD animal biosafety level-3 (ABSL-3) facility.
Project 4: Repurposing FDA-approved cancer drugs (kinase inhibitors) to treat neurological disorders.
Student responsibility: Medical students must have experience of animal surgery and are interested in therapeutics for neurological disorders. Students working in the Liu team are expected to commit several hours per week to search literature, learn animal surgery, write a mini-review, and complete project design during the school year. The students should dedicate fixed time for research after year 1 to conduct bench work and write a grant if data and time are sufficient.
Training plan: The interested students are encouraged to participate in Project 4. Open below link for the rationale and examples of this project in a perspective entitled “Repurposing cancer drugs to treat neurological diseases–Src inhibitors as examples” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5514862/.
Under Dr. Liu’s instruction, the students working in the Liu team will learn to design and execute a project by: 1) searching literature; 2) selecting a drug from the 62 FDA approved kinase-targeted cancer drugs; 3) picking animal models of an interested neurological disorders, such as TBI, stroke, AD, autism, epilepsy, MS, PD, and others (Note: In the event that the Liu team does not have animal models of a neurological disorder that a student is interested in, the student will be referred to other faculty of interest); 4) testing the therapeutic efficacy of the selected drug using animal models; 5) analyzing data and writing grant.
The long-term goal is to advance experimentally effective cancer drugs to clinical trials for treatment of certain types of neurological disorders in collaboration with physicians, which allows the students to continuously involve this project if they join Medical Schools at the UCD after graduation.

Plant Pathology, Kearney Agricultural Research & Extension Center (KARE), Parlier, CA
Dr. Michailides is a leading authority in fungal fruit tree pathology and is nationally and internationally recognized for his innovative ecological, epidemiological and plant disease management studies of devastating diseases of fruit crops such as the brown rot of stone fruit (pre-harvest and post-harvest), Botrytis gray mold of kiwifruit, pomegranate, and pistachio, fig endosepsis and smut of figs, black heart of pomegranate, Botryosphaeria blight and canker of pistachio, almond, and walnut, and aflatoxin contamination of nut crops and figs. We are doing pioneering work on resistance mechanisms of Alternaria alternata and Botrytis cinerea to various fungicides. Our studies also involve the phylogenetic analysis and taxonomy of plant pathogens attacking fruit and nut tree crops and determination of resistance of various tree cultivars to plant diseases. We focused on detection of pathogens’ latent infections; these studies helped develop practical techniques that are used now commercially by private laboratories to help pest control advisers, California growers, and growers worldwide to make wise decisions regarding disease management. A very recent major accomplishment was the registration of an atoxigenic Aspergillus flavus strain AF36 (inoculum carrier wheat seed) in pistachio to reduce aflatoxin contamination of pistachio. About 77,000 acres of pistachios were treated with AF36 in 2012 for the first time and about 150,000 to 200,000 acres in 2013, 2014, and 2015. We also performed studies to expand the label of AF36 registration for almonds and figs. Registration was obtained for the atoxigenic Aspergillus flavus AF36 Prevail (inoculum carrier sorghum seed) in early August 2017. Funding and collaborations on these projects include the California Pistachio Research Board, the Almond Board of California, the California Fig Institute and other Agricultural Industries, the California Department of Food and Agriculture, and the Agricultural Research Service (ARS) of the USDA. In addition, there is a crew of 8 to 10 people doing research in my plant pathology projects at the KARE Center, so there is ample opportunity for interaction with a variety of individuals in an area of fundamental and traditional plant pathology.

Tendon repair, tendon stem/progenitor cell biology; broiler muscle pathology; foal microbiome
My primary research interests include:
(1) the development, maturation, and repair of musculoskeletal connective tissues like tendon and ligament
(2) cellular mechanisms behind broiler muscle pathology
(3) the roles of the microbiome in proper gut transition in foals from birth to weaning.
In my musculoskeletal research projects, I am particularly interested in how differences in niche affect cells within the environment in growth and repair. Moreover, I am interested in the physiology of usage and elite performance as well as pathophysiology from over-usage, acute and chronic injury for all musculoskeletal tissues on all species as they might be related to use, environment, or genetics, and as they might be related to the manipulation of niche and collagen regulation genes. Furthermore, because the proper development of the musculoskeletal system depends greatly upon proper foal growth and foal growth subsequently depends upon appropriate nutrition, I am interested in understanding how gut microbes facilitate healthy gut transitions in the foal.

Department of Poultry Health and Food Safety Epidemiology
My focus is on poultry health and food safety epidemiology. From a poultry health perspective we work on GIS based approaches toward understanding how diseases move in space and time in order to better mitigate the spread of zoonotic and epizoonitic diseases.
From a food safety perspective my interests are primarily associated with Salmonella. Specifically from a molecular perspective we are exploring the use of next generation sequencing technologies to better understand the virulence and pathogenicity of Salmonella Heidelberg.
California is a national and global leader in sustainable agriculture. Because of this, the development of ‘micro-commercial’ poultry facilities (smaller than 3,000 hens/broilers) has mushroomed. Due to their relatively small size they are largely ignored with respect to food safety and poultry health. Our group is interested in learning more about these type of producers in order to understand their practices from a sustainability perspective and food safety perspective.
Possible 10-week introductory research projects include:
- Researching the ‘transcriptome’ (i.e. gene expression) of Salmonella Heidelberg. Student would learn Next Generation Sequencing laboratory based techniques and data analysis tools.
- GIS based tools for monitoring avian diseases. Student would use ArcGIS based software coupled with other data analysis tools to analyze avian diseases (some background in GIS preferred).
- Student would help develop, administer, and analyze data related to micro-commerical poultry production in California.

Although thought of as disparate fields of study, these two systems have co-evolved and are now appreciated to influence each other. Dr. Reardon’s research focuses on the modification of immune outcomes by neurotransmitters, and on the recently discovered production of the neurotransmitter acetylcholine (Ach) by B- and T-cells. Dr. Reardon’s research has previously identified that the commensal microbiota is involved in the regulation of Ach production by these immune cells. . Various projects are currently ongoing in the laboratory that will seek to establish the role of specific neurons in modulating immunopathologies, including inflammatory bowel disease and diabetes. Based on this, testing of small molecule agonists, and neurostimulator devices (in collaboration with biomedical engineers) to modulate immunopathologies will be performed in the laboratory. To accomplish this a variety of complementary techniques will be used including flow cytometry, confocal and intravital microscopy.
If interested, please contact Dr. Reardon email@example.com.

Dr. Ripplinger has a PhD in Biomedical Engineering and advanced training in imaging and physiology. The focus of her research is on using high-speed and molecular imaging techniques to study basic mechanisms of cardiac arrhythmias. Her lab develops and studies pathologic arrhythmias in rodent and rabbit models of cardiovascular disease including healed myocardial infarction, acute ischemia, and heart failure. In vivo and ex vivo imaging on hearts of these animals is then performed to elucidate arrhythmia triggers and discover new anti-arrhythmic strategies. Possible summer research projects for veterinary students include 1) investigating mechanisms of triggered arrhythmias in a rabbit model of heart failure; and 2) investigating the role of inflammation in mediating arrhythmia following myocardial infarction. Both projects involve rodent and rabbit surgery, in vivo and ex vivo imaging, and image analysis.
Please email Dr. Ripplinger for more information at: firstname.lastname@example.org or call (530) 752-1569.
Dr. Rivera-Nieves works on the pathogenesis of Crohn’s disease. Leukocytes of the granulocytic, monocytic and lymphocytic lineages are active participants in the chronic inflammatory process. Their recruitment from the circulation is regulated by adhesion molecules and chemokine receptors interacting with their respective ligands expressed or presented by intestinal endothelia cells. These adhesive interactions represent attractive therapeutic targets for the modulation of the destructive chronic inflammatory process. Proof of concept for the viability of this strategy has been provided by the efficacy of natalizumab, which interferes with integrin alpha-4-VCAM-1, MAdCAM-1 interactions. Using novel murine models of Crohn’s-like ileitis, Dr. Rivera-Nieves has continued to explore potential molecules that may be targeted, within the leukocyte recruitment cascade.

Dr. Rumbeiha is a veterinarian and a toxicologist with interest in both translational and basic toxicology research. His current translational research projects revolve around developing diagnostic tests to confirm animal intoxications. His current basic research projects are revolving around understanding mechanisms of hydrogen sulfide-induced toxicity using animal models (mice and pigs) and in vitro cell culture techniques. Hydrogen sulfide is an interesting molecule which is produced naturally in vivo and plays key physiologic roles as a gasotransmitter akin to nitric oxide. It is also an environmental pollutant with multisystemic effects on the central nervous system, the respiratory, and the cardiovascular systems. Toxic outcomes vary depending on whether exposure is acute or chronic. In case of acute exposure, some effects are immediate while others are like neurodegeneration, are delayed. At low ambient chronic exposure levels my laboratory is studying the interaction between hydrogen sulfide and influenza A virus, a respiratory tract pathogen. The interaction between environmentally relevant concentrations of toxicants and infectious disease pathogens is a promising area of research which has received little attention. We use multiple techniques from molecular biology, neurotransmitter analysis, in vivo imaging, and behavioral assays in our investigations.
If interested in getting involved, please contact Dr. Rumbeiha email@example.com.

Research in the Segal Lab revolves around engineering zinc finger, TALE, and CRISPR/Cas nucleases and transcription factors. Almost every disease has a genetic component. Often this information is used only to determine how condemned a person is to develop disease. We would like to use the genetic information to fix the disease. A guiding principle for our work has been to study how nature does what it does, then attempt to use that knowledge to make useful tools to improve public health. We continue to develop new methodologies for genome editing. Our most recent efforts focus on creating epigenomic editing tools that can precisely manipulate epigenetic information at specific loci. Such tools can be used for the long-term control of gene expression for both research and therapeutic applications. Angelman syndrome is a rare neurogenetic disease that is the textbook example of an imprinting disorder. We are using artificial transcription factors to activate the epigenetically silenced gene in in the brains of mice and other animal models.

Our laboratory investigates the spread of prion diseases. We are focused on understanding the molecular basis for prion transmission between species, for example, human and animal susceptibility to prions of deer and elk, known as chronic wasting disease. To this end, we have identified a loop region in the prion protein that has a major impact on the cross-species transmission of prions. We also study how the prion aggregates spread from cell-to-cell within the brain, leading to fatal neurodegeneration.
A third area of interest is in understanding the molecular basis of the toxicity occurring in prion disease. Aggregates of prion protein lead to neuronal degeneration and inflammation, however the mechanisms are poorly understood.
We would welcome veterinary students to our laboratory at UC San Diego to participate in projects related to prion disease and neurodegeneration.

Assessment of antiviral cellular immune responses in the prevention of FIP in cats infected with feline infectious peritonitis coronaviruses.
Assessment of receptor tyrosine kinases (RTK) as targets for cancer therapeutics in feline oral squamous cell carcinoma (OSCC).
Project Appropriate for a Star Student Summer Project:
A feasible project for a Star Student would involve examination of tumor biopsies from clinical cases of feline OSCC for expression and mutation of specific RTKs. This project would include extraction of DNA and/or RNA from tumor tissues followed by PCR amplification of sequences specific to RTKs, including epidermal growth factor receptor (EGFR) and cKit and possibly other RTKs. PCR products would next be sequenced for detection of possible mutations involving activation domains of these proteins. The student involved in this project would perform research in the laboratory of Dr. Sparger but also work with Dr. Katherine Skorupski in the Veterinary Oncology Service to facilitate the collection of biopsies from clinical patients as well as become familiar with this significant cancer entity in cats for which there is no effective therapeutic protocol. Assimilation of clinical data with correlation of RTK expression and sequence will require the student to work closely with both Drs. Sparger and Korupski. Assessment of RTKs in feline OSCC will be critical for determination of which tyrosine kinase inhibitors currently in use for human OSCC, might be effective for feline OSCC as well. This project is part of a larger effort by Drs. Sparger, Korupski, Michael Kent, Boaz Arzi, and Brian Murphy to characterize feline OSCC as a model for human head and neck cancer.

VMTH Behavior Service
Research interests: Companion Animal Behavior and Welfare
The Behavior Service does research on many aspects of companion animal behavior, welfare, and the human-animal bond. Current studies involve the role of environmental stressors and personality on the development of urolithiasis in cats and the transition of singly-housed colony Orange Winged Amazon (OWA) parrots into a co-housing setting.
The best opportunity for a STAR project is within the OWA study. Recent laboratory animal housing guidelines are driving the changes in housing for these birds and little existing research is available to educate the transition process. Those factors make this a groundbreaking research project, several aspects of which could be tailored to a stand-alone STAR project for the right student.
Other student-proposed research ideas in the area of animal behavior will be considered individually.

James S. Trimmer studies how voltage-gated ion channels are modulated in response to physiological and pathophysiological alterations in hippocampal neuronal activity. His primary experimental approach is to manipulate hippocampal neuronal activity, in either animals in vivo, in organotypic slice cultures or in dissociated neuronal cultures, and analyze effects on phosphorylation as a regulator of ion channel expression, localization and function. These studies use time-lapse and confocal imaging, patch-clamp recording, analyses of phosphorylation state employing phospho-specific antibodies and mass spectrometry, immunohistochemistry, and immuno-electron microscopy. Much of our recent work involves the colocalization of ion channels proteins to specific sub cellular domains, a subject that would be greatly enhanced by studies at the ultra structural level. Access to this highly specialized technology is absolutely essential for our future research plans.

Dr. Tsolis is a microbiologist studying host-pathogen interactions leading to disease during infection. Her laboratory uses a variety of animal models to study how two groups of zoonotic pathogens, non-typhoidal Salmonella and zoonotic Brucella species, interact with the immune system to cause disease. For non-typhoidal Salmonella species, Dr. Tsolis' group is interested in learning why underlying co-morbidities such as malaria and malnutrition increase the incidence of death from systemic infection in the developing world, and her laboratory has developed mouse models to gain insight into immunomodulatory effects of Vitamin A deficiency and malaria. For Brucella, the laboratory has developed models to understand both chronic infection that this group of organisms causes within the mononuclear phagocyte system and to interrogate placental infections in pregnant animals that lead to abortion in domestic animals. Collaborations with UCD research Dr. Luckhart in the Medical Microbiology department, Dr. McSorley in the Center for Comparative Medicine and Dr. Stephensen in the USDA Western Human Nutrition Research Center have been instrumental in establishing this interdisciplinary research program. The long-term goal of Dr. Tsolis' work is to uncover basic principles of how bacterial pathogens manipulate the immune response to cause disease and ensure their transmission to the next host.

The Woolard Laboratory is primarily focused on comparative biology of human and canine glioma brain tumors. These tumors have an aggressive biologic behavior, with median survival times of around 14 months in people, in spite of surgery, chemo-, and radiotherapy. Much of our efforts are focused on identifying how sub-populations within an individual patient’s tumor communicate with each other to establish a dominant population of tumor cells, as well as how cells re-grow following initial treatment. We are also examining how cellular metabolism in glioma may impact epigenetic dysregulation, with the goal of providing a druggable target to delay tumor progression. Finally, we also routinely isolate canine embryonic neural stem cells, which are used as physiologic comparisons to glioma tumor cells. Additionally, we are using these cells to model Zika virus infection in mammalian neural stem cells.
