The Department of Molecular and Comparative Pathobiology (formerly comparative medicine) obtained one of the first NIH training grants for postgraduate training of veterinarians and has been funded continuously for over 35 years. We combine intensive training in comparative pathology during the first year of the program and research mentored by outstanding scientists in the final three years. More than 110 veterinarians have been trained in the department; many are now department chairs and leaders in academia and industry worldwide.
