'About Molecular Biosciences Department

The Department of Molecular Biosciences serves as the academic home for all nutritional, physiological chemistry, and pharmacologic and toxicologic programs of the School of Veterinary Medicine at UC Davis. Our goal is to study fundamental biological processes and their perturbations by mutations, nutrition, drugs and xenobiotics and the application of these to the improvement of animal and human health. Faculty participate in a number of graduate groups including Genetics, Microbiology, Neurosciences, Nutritional Biology, Biochemistry, Molecular, Cellular & Developmental Biology, and Pharmacology & Toxicology. The department also contributes substantially to school and campus initiatives in Environmental and Human Health. Faculty include toxicologists at the California Animal Health and Food Safety Laboratory System (CAHFS) and provide expertise for the Equine Analytical Program of the State of California. The department also shares responsibility for the Clinical Pharmacology, Clinical Toxicology, and Clinical Nutrition Programs, including the Nutrition Service at the VMTH.
