Kelly A. Metcalf Pate, DVM, PhD, the Director of the Division of Comparative Medicine. Dr. Metcalf Pate is a veterinarian-scientist with expertise in virology, platelet immunology and the development and refinement of animal models of human disease. She received her B.A. through the University Professors Program at Boston University, obtained her D.V.M. from Purdue University College of Veterinary Medicine, and pursued both veterinary specialty training in laboratory animal medicine and her Ph.D. at Johns Hopkins School of Medicine.

Prior to joining M.I.T., she was faculty at Johns Hopkins School of Medicine, where she facilitated the development and refinement of animal models of HIV pathogenesis as a chair of the Center for AIDS Research Cure Scientific Working Group, and oversaw the research training programs for veterinarians and veterinary students and founded the J.H.U. summer Veterinary Scholars Research Program and the summer Laboratory Animal Fellowship.

Dr. Metcalf Pate has served on multiple national committees, including on the National Academies of Sciences and Medicine (NASEM) Committee on the Nonhuman Primate Model Systems: State of the Science and Future Needs, and on the NIH Advisory Committee to the Director Working Group on Catalyzing the Development and Use of Novel Alternative Methods to Advance Biomedical Research. Passionate about inspiring the next generation of comparative medicine professionals to engage in research, she serves on the planning committee for the National Veterinary Scholars Symposium.

Tiffany M. Borjeson, DVM, DACLAM, CPIA is the Associate Director of the Division of Comparative Medicine. Dr. Borjeson received her veterinary degree from the Virginia-Maryland Regional College of Veterinary Medicine and completed her postdoctoral residency in comparative medicine through the training program at MIT. She has extensive experience in protocol and animal model development, with an expertise in cardiovascular surgery and transgenesis.

Prior to returning to MIT, she served as the Associate Director at Brown University’s Center for Animal Resources and Education and as an Adjunct Professor / interim Director of Animal Resources in the Department of Biomedical Sciences and Pathobiology at Virginia Tech. She also serves as an ad hoc Consultant for AAALAC International.

In her role as Associate Director at MIT, Dr. Borjeson provides both broad programmatic oversight and direct clinical care to research animals.

James G. Fox, DVM, MS, DACLAM, is a Professor and Founding Director of the Division of Comparative Medicine and a Professor in the Department of Biological Engineering at the Massachusetts Institute of Technology. He is also an Adjunct Professor at Tufts University School of Veterinary Medicine and the University of Pennsylvania, School of Veterinary Medicine.

Professor Fox is the author of over 625 articles, 80 chapters, 3 patents and has edited and authored 15 texts in the field of in vivo model development and comparative medicine. He has served on the editorial board of several journals and is a past member of the NIH/NCRR Scientific Advisory Council. He has received numerous scientific awards including the AVMA’s Charles River Prize in Comparative Medicine, the AALAS Nathan Brewer Scientific Achievement Award, the AVMA Excellence in Research Award, the ACLAM Award for Scientific Achievement, the Pravin Bhatt award for research excellence and the AALAS Griffin Award.

He has been studying infectious diseases of the gastrointestinal tract for the past 40 years and has focused on the pathogenesis of Campylobacter spp. and Helicobacter spp. infection in humans and animals. His laboratory developed the ferret as a model for both campylobacter and helicobacter associated disease as well as the first rodent model to study helicobacter associated gastric disease including gastric cancer.

Dr. Fox is considered an international authority on the epidemiology and pathogenesis of enterohepatic helicobacters in humans and animals. He is largely responsible for identifying, naming, and describing many of the diseases attributed to various Helicobacter species; most notably their association with hepatitis, liver tumors, inflammatory bowel disease and colon cancer in mice. His laboratory most recently has described the pivotal role that Helicobacter spp. play in the development of the gallstones in mice fed a lithogenic diet; thus linking this finding to his earlier description of Helicobacter spp. associated chronic cholecystitis and gallstones in Chilean women, a population at high risk of developing gallbladder cancer. He also has had a long-standing interest in zoonotic diseases as well as biosafety issues associated with in vivo models.

His past and current research has been funded by NIH and NCI, as well as by private industrial sources, for the past 40 years. He has been the principal investigator of an NIH postdoctoral training grant for veterinarians for the past 29 years. He consults nationally and internationally with government, academia and industry. In 2004 Professor Fox was elected to the National Academy of Medicine of the National Academy of Sciences.
