Geof Smith received a BS in animal and dairy science from Clemson University in 1994. From there he received a MS in toxicology from University of Illinois in 1996 and a DVM in 1998. Following graduation, Geof remained at the University of Illinois for another 4 years while he completed an internship and residency in ruminant internal medicine along with a PhD in physiology. Dr Smith joined the faculty at North Carolina State University in 2002 and is currently a Professor of Ruminant medicine in the Department of Population Health & Pathobiology. He is a Diplomate of the American College of Veterinary Internal Medicine (ACVIM) and his primary clinical and research interests revolve around clinical medicine of ruminants with a specific focus on calf health and ruminant pharmacology.
