Agricultural Experiment Station (AES) Faculty

Within the University of California system there are Instruction and Research (I&R) faculty with AES appointments meaning that in addition to their instruction and research responsibilities they engage various stakeholders groups in order to disseminate science based information to California farmers and other interested parties.

ANTIMICROBIALS

Dr. Richard Van Vleck Pereira

Dr. Richard Van Vleck Pereira’s research focus is on the epidemiology of antimicrobial resistance and enteric pathogens of importance to humans and domestic animals. Dr. Pereira’s studies comprises field and laboratory experiments to evaluate and quantify the impacts of dosing and treatment regimens of specific antimicrobials in food animals. Recent emphasis areas include impacts of drug residues on selection of antimicrobial resistance and disruption of enteric microbiota (e.g. ingestion of waste milk by calves), and effects on animal health and farm management from recent legislation changes related to antimicrobial drug use in food animals (e.g. The FDA’s Veterinary Feed Directive and California Senate Bill-27).

Dr. John Angelos

Dr. John Angelos' research focus is on the pathogenesis and prevention of infectious bovine keratoconjunctivitis (IBK; ‘pinkeye’), the most common eye disease of cattle. Dr. Angelos is currently exploring intranasal vaccination to prevent IBK and the development of better adjuvants to stimulate mucosal immunity against pathogenic factors from bacterial agents implicated in causing IBK.

Dr. Rodrigo Gallardo

Dr. Rodrigo Gallardo’s research focus is on poultry respiratory diseases with an emphasis on avian influenza (AI), Newcastle disease and infectious bronchitis. Specifically, Dr. Gallardo studies genetic variation, viral interaction with the host, viral persistence and methods of prevention associated with poultry respiratory diseases. Dr. Gallardo also investigates other diseases causing losses in commercial poultry such as avian Reoviruses and encephalomyelitis. Finally in order to address food insecurity issues in California Dr. Gallardo is also working with small poultry flock owners in order to address poultry health and management issues including the prevalence and risk of poultry respiratory diseases in backyard flocks.

Dr. Laurel Gershwin

Dr. Laurel Gershwin’s research focus is on bovine respiratory disease complex (BRDC) with particular emphasis on the immune response to bovine respiratory syncytial virus. This disease is important to dairy calves and to feedlot cattle and is a major cause of economic loss to the cattle industry. The Gershwin laboratory has collaborated on a multistate project to study genetic susceptibility to BRDC. Most recently we have developed and tested a subunit vaccine for two of the major pathogens of the BRDC. Continuing studies focus on the use of immune modulator drugs and an antiviral drug to treat bovine respiratory syncytial virus infection.

Dr. Meera Heller

Dr. Meera Heller’s rresearch focus is in juvenile immunity and the innate immune system, with respect to susceptibility to infectious diseases and whether we can augment the innate immune system to prevent disease.  Dr. Heller’s current research focuses on bovine respiratory disease with cross-interest in intracellular pathogens, other calf-hood diseases and acupuncture and its uses in food producing animals as a strategy to increase welfare and reduce drug residues.

Dr. Terry Lehenbauer

Dr. Terry Lehenbauer’s research focus is on epidemiology of infectious diseases with respect to clinically important diseases of dairy cattle, including bovine respiratory disease and mastitis, and the relationships of those infectious diseases to preventive health and other strategies that will promote antimicrobial stewardship.

Dr Martinez Lopez

Dr Martinez Lopez’s research focus is on disease modeling and surveillance research with a focus on understanding the emergence, evolution and spread of infectious diseases, including those at the wildlife-domestic-human interface. In addition, Dr. Lopez’s uses the above information to provide science based recommendations to more cost-effectively prevent, control, or eradicate animal diseases and mitigate their associated adverse economic impacts. Dr. Lopez is the director of the Center for Animal Disease Modeling and Surveillance (CADMS) which serves as a core research program for faculty and students interested in animal disease modeling and surveillance research.

Dr. Jim MacLachlan

Dr. Jim MacLachlan’s research focus is on viral diseases of livestock that impact international commerce including emerging diseases such as bluetongue and African horse sickness that are transmitted by Culicoides biting midges. Bluetongue virus infection of cattle and other domestic and wild ruminants occurs throughout much of the United States, including California, and is of increasing global concern. In order to help mitigate the spread of these diseases, Dr. MacLachlan has served as an expert advisor to numerous organizations including the World Organization for Animal Health (O.I.E), the United States Departments of Agriculture, Homeland Security, and the European Union.

Dr. Birgit Puschner

Dr. Birgit Puschner's research focus is on the impact of toxicants on animal and human health. Toxicants of interest include naturally toxins, such as the cyanobacteria-produced toxin microcystin, and man-made chemicals such as PCBs. Dr. Puschner is particularly interested about the movement of toxicants through the body and the implications to public health from incurred residues in food derived from animals. Her work involved analytical testing to provide quantitative measures of toxicant exposure and correlating those to specific endpoints.
