Surgery, Emergency and Critical Care


Oral and Maxillofacial Research

(See also: Dentistry, Diagnostic Imaging, Pathology/Virology)

My current research fields are 1) regenerating the mandibular bone after resective surgery or due to defect non-unions. This project combines the use of BMP-2 and a scaffold and efforts towards understanding stem-cells recruitments locally and systemically 2) adipose-derived mesanchymal stem cells for the treatment of feline gingivostomatitis. 3) the biomechanics and kinematics of mandibular reconstruction in dogs and cats 4) Temporomandibular joint (TMJ) disorders, diagnistics and treatments studies. These projects extend and bridge the clinical practice at the UC Davis VMTH on one side and basic and regenerative laboratory science on the other side.

The summer STAR project is intended to take place at UC Davis.

The 2019 summer STAR project is entitled “Cone Beam Computed Tomography (CBCT) and pathology of canine temporomandibular joint osteoarthritis: an agreement study” and will be done with collaboration with Dr. Derek Cissell.

Jamie Burkitt, DVM, DACVECC

Assistant Professor of Clinical Small Animal Emergency and Critical Care

Dr. Burkitt is an assistant professor of clinical small animal emergency and critical care in the VMTH. Her main research interests lie in better understanding and preventing recurrence of urethral obstruction in male cats. Dr. Burkitt is just starting her research projects in the VMTH and is interested in retrospective and prospective data collection and analysis regarding factors that can help prevent recurrence of this devastating disease in male cats.

Ronald Li, DVM, MVetMed, DACVECC

Department of Surgical and Radiological Sciences 

(See also: Biochemistry/Cellular Biology, Immunology/Infectious Diseases)

Dr. Li is a small animal criticalist and platelet-neutrophil biologist in the department of Surgical and Radiological Sciences.  The Li Comparative Platelet and Neutrophil Physiology Laboratory focuses on platelet and neutrophil interaction in health and diseases, immune and hemostatic function of platelets and the testing of anti-platelet therapies in small animals.  Currently Dr. Li is working on projects related to the impact of genetic polymorphisms in cats with hypertrophic cardiomyopathy on clopidogrel therapy and platelet activation.  His laboratory is also investigating the role of platelet-derived high mobility group box-1 in platelet activation and neutrophil extracellular trap formation in dogs and cats.

Aijun Wang, PhD

UC Davis Medical Center, Department of Surgery (see also: Translational Research, Orthopedics, Biochemistry)

My name is Aijun Wang. I am an assistant professor at the Department of Surgery, School of Medicine. My research interests center on engineering stem cells and biomaterials to develop novel regenerative medical therapies, especially surgical treatments for congenital anomalies. Since my employment as Co-Director of the Surgical Bioengineering Laboratory and an Assistant Professor at the University of California Davis School of Medicine in 2012, my lab has successfully combined tissue-engineering technologies with the most advanced fetal intervention, and developed novel biomaterial and stem cell-based treatments (including nanofibrous materials, fetal membrane, decelluarized extracellular matrix, iPSC-derived stem cells, placenta-derived stem cells) for devastating structural and genetic birth defects, such as spina bifida, hemophilia and congenital diaphragmatic hernia. Currently, we are extensively using the mouse, rat, guinea pig, rabbit and sheep experimental models to develop novel regenerative therapies. We are also adapting these novel therapies we developed in the lab for the treatment of naturally occurring diseases in companion animals.
