Faculty in the Division of Comparative Pathology and Medicine

The Center for Veterinary Sciences and Comparative Medicine includes the members of the Division of Comparative Pathology and Medicine, and an accredited residency program in Laboratory Animal Medicine. This Center is overseen by The Faculty of Health Sciences at UCSD which also oversees the School of Medicine and the School of Pharmacy. This Center also creates collaborative learning and research opportunities with UC Davis.

There are more than 20 veterinarians at UC San Diego and the nearby outstanding, research institutions, including The Scripps Research Institute, the Salk Institute, the La Jolla Institute for Allergy and Immunology, the Sanford-Burnham Institute, the San Diego Zoo and San Diego Wild Animal Park, the Marine Mammal Foundation, Sea World San Diego, and the La Jolla Laboratories of Pfizer.

Lynette Corbeil, DVM, PhD

Lynette Corbeil, D.V.M., Ph.D.
Professor of Pathology, UC San Diego
Emeritus Professor of Population Health and Reproduction School of Veterinary Medicine UC, Davis
Former Co-Director, UC San Diego Veterinary Medical Center

Our general research interests are in the area of comparative (human to mouse) mucosal immunology with specific projects in immune-epithelial cell interactions involved in the microbial pathogenesis of acute and chronic diseases of the gastrointestinal tract.

Pascal Gagneux, Ph.D.

Pascal Gagneux, Ph.D.
Associate Professor of Pathology, UC San Diego

Pascal Gagneux is interested in the evolution of cell-surface glycans. Glycans are diverse and variable saccharide chains attached to proteins and lipids. Glycans can differ by species, individual, cell type, and even physiological state or developmental stage. Glycan variation influences many phenotypes: from cellular recognition during fertilization and development, to infection, immunity, and cancer. So far, we know little about the evolutionary forces that shape glycan variation. This is an important gap in our knowledge, because glycans are central to cellular recognition, and to health and disease.

Nikos Gurfield, DVM, DACVP

Nikos Gurfield, D.V.M., D.A.C.V.P.
Adjunct Professor of Pathology, UC San Diego
County Veterinarian
San Diego County Vector Disease and Diagnostic Laboratory

Dzung Le, M.D., Ph.D.

Dzung Le M.D., Ph.D.
Director of the Coagulation Laboratory
Associate Director of the Clinical Hematology Laboratory
Associate Director of Blood Bank and Transfusion Medicine
Associate Professor of Pathology

My research interests are tissue factor-initiated coagulation pathway and clinical coagulation assay development. My research laboratory also houses the Murine Hematology/Chemistry and Coagulation Core laboratory. This core laboratory tests for abnormalities in hematology, chemistry and coagulation in experimental mice (e.g., transgenic mice).

Robert Naviaux, MD, PhD

Robert Naviaux, M.D., Ph.D.
Professor of Medicine, Pediatrics, and Pathology

Research in my lab has focused on the role of mitochondrial DNA replication, copy number regulation, DNA damage, and nucleotide signaling in development, aging, healing and regeneration. We also study the systems biology of monogenic and complex diseases like autism and diabetes.

Kent Osborn, D.V.M., Ph.D.
Associate Director, Animal Care Program (ACP), UCSD

Dr. Osborn's professional activity has often included broad-spectrum practice of laboratory animal medicine (clinical, diagnostic, administrative, compliance) and comparative pathology. Particular areas of interest include infectious disease - pathophysiology, diagnostics and control/prevention in populations; comparative pathology; animal-related ethics.

G. Diane Shelton, D.V.M, Ph.D.

G. Diane Shelton, D.V.M., Ph.D.
Director of The Comparative Neuromuscular Laboratory
Professor of Pathology

My research interests are in understanding the mechanisms of autoimmunity in myasthenia gravis and inflammatory myopathies. Research in canine models of these diseases has direct relevance to their human counterparts.

Dr. Sigurdson
Christina Sigurdson, D.V.M., Ph.D., Dipl. ACVP

Co-director of the Center for Veterinary Sciences and Comparative Medicine
Associate Professor of Pathology

We are interested in the molecular pathogenesis of prion diseases, which are fatal neurodegenerative disorders of humans and animals that includes Creutzfeldt-Jakob disease (CJD), bovine spongiform encephalopathy (BSE) or “mad cow disease”, and chronic wasting disease (CWD) of cervids. We are investigating mutations in the prion gene that enable or inhibit prion transmission between species.

Nissi M. Varki, M.D.
Nissi Varki, M.D.
Director of Histopathology Resources, Cancer and Mouse Histopathology
Professor of Pathology
Our research interests are to define the role of selectins in tumor metastasis. We are working toward an understanding of the uniqueness of human carcinogenesis. We also study the histopathology of antiangiogenic agents in mouse models and the immunological mechanisms of gastrointestinal mucosal epithelia.
