Dr. Williams received his A.S. degree from Collin County Community College in 1997.  Dr. Williams subsequently received his B.S. degree in the study of Biology from the University of Texas at Dallas in 1999. In 2006, he completed his Ph.D. in Neuroscience from Tulane University in New Orleans, where he worked with Dr. Bret N. Smith (currently at the University of Kentucky). He joined the Division of Hypothalamic Research in the Department of Internal Medicine here at UT Southwestern, following completion of his postdoctoral studies with Dr. Joel K. Elmquist.  His lab uses mouse genetics, electrophysiology, and systems neuroscience approaches to study the cellular mechanisms within the brain which may underlie the coordinated control of food intake, body weight, and glucose homeostasis.

Honors & Awards

  • Timothy J. Bartness Award
    This endowed award honors Dr. Timothy J. Bartness who was a Regent's Professor of Biology at Georgia State University and an eminent researcher of the neural control of adipose tissue, obesity and ingestive behaviour. He was a past-president of Society for the Study of Ingestive Behavior (2008-2009) and an ardent champion of early career investigators. In keeping with his tireless advocacy for junior scientists and dedication to mentorship, this award is given for the best oral presentation at the annual meeting by a junior faculty member. Members of SSIB. (2019-2019)
  • The Novo Nordisk – Helmholz Young Investigator Diabetes Award (HeIdi Award) Nominee
    This high impact conference brings together international top leaders in the field of diabetes to facilitate the identification of, and potential solutions to, the preeminent scientific challenges facing the prevention and treatment of type 2 diabetes. The conference features a focus on the brain in control of metabolism, and two award presentations: the Helmholtz Diabetes Lecture, in recognition of the lifetime achievements of a senior leader in the field, and the Novo Nordisk - Helmholtz Young Investigator in Diabetes (HeIDi) Award, in recognition of a rising star.
