David A. Williams - Idiopathic Chronic Enteropathy in Older Cats



David A. Williams, MA, VetMB, PhD, DACVIM, DECVIM University of Illinois, School of Veterinary Medicine

Dr. David Williams received his veterinary degree from the University of Cambridge and his PhD from the University of Liverpool, where he first developed the canine trypsin-like immunoreactivity (cTLI) assay. He completed an internship and residency at the University of Pennsylvania and has held faculty positions at the University of Florida, Kansas State University, Purdue University, Texas A&M University, and the University of Illinois at Urbana-Champaign. While at the University of Florida, Dr. Williams founded the GI Lab in 1985, when he introduced the TLI assay for use in dogs to the U.S. His research has focused on the development and application of new tests for gastrointestinal diseases, particularly those affecting the pancreas (TLI, pancreatic lipase) and small intestine (cobalamin, folate) of dogs and cats. His current research is directed at the relationships between the intes­tinal microbiome and metabolomics changes elsewhere in the body in aging cats with idiopathic chronic enteropathy and in both dogs and cats with exocrine pancreatic insuffi­ciency. Dr. Williams continues to work as a consultant with the GI Lab at Texas A&M University, providing telephone consultations regarding management of patients diagnosed using the GI Lab services.
