David Williams, MA, VetMB, PhD, DACVIM, DECVIM-CA

Nearly three decades ago, David Williams founded the GI Lab at the University of Florida, when heintroduced the canine serum trypsinlike immunoreactivity (TLI) assay to the United States. His research has focused on the development and application of new tests for gastrointestinal diseases, particularly those affecting the pancreas, small intestine, stomach, and liver of dogs and cats. Students and staff working in his other GI laboratories at Kansas State University, Purdue University, and Texas A&M University have established several other novel tests for gastrointestinal diseases. These included feline serum TLI, canine and feline serum pancreatic lipase, canine and feline fecal alpha1-proteinase inhibitor, unconjugated serum bile acids, canine thyroid stimulating hormone, and canine and feline serum cobalamin and folate assays. Dr. Williams received his veterinary degree from the University of Cambridge and his PhD from the University of Liverpool. He has held faculty positions at the University of Florida, Kansas State University, Purdue University, Texas A&M University (where he served as head of Small Animal Clinical Sciences), and currently at the University of Illinois (where he served as head of Veterinary Clinical Medicine). He continues to work as an adjunct professor and a consultant with the GI Lab at Texas A&M University.
