Biography/Professional Experience

Dr. Kathryn Bach is an Assistant Professor of Practice in the Department of Population Medicine and Diagnostic Sciences. She received her VMD from the University of Pennsylvania with a production animal focus, and further training in livestock medicine and population health at Colorado State University. Dr. Bach received her MS and PhD from Cornell University where she studied semen cryopreservation and methods of subclinical disease monitoring in periparturient dairy cattle, respectively. During her PhD, she was actively involved in teaching in the preclinical veterinary curriculum, both as a lecturer and a laboratory instructor.

Dr. Bach’s main lecturing responsibilities are in Foundation Course III, Function and Dysfunction. Additionally, she teaches Ruminant Anatomy and is the Program Coordinator for the Summer Dairy Institute, an advanced training program for prospective dairy veterinarians.
