Rodney Infante, M.D., Ph.D., is an Associate Professor in the Center for Human Nutrition at UT Southwestern Medical Center, with secondary appointments in the Department of Molecular Genetics and the Department of Internal Medicine, where he is a member of its Division of Digestive and Liver Diseases. He specializes in general gastroenterology and cancer cachexia.

Dr. Infante holds a bachelor's degree in accounting from the University of Florida in Gainesville, where he graduated with honors. He earned his medical degree from UT Southwestern Medical School and his doctorate from UT Southwestern Graduate School of Biomedical Sciences, where he studied intracellular lipid trafficking under the tutelage of Michael Brown, M.D., and Joseph Goldstein, M.D. He then completed internal medicine residency training at Massachusetts General Hospital in Boston, and returned to UT Southwestern for advanced fellowship training in gastroenterology and human nutrition. 

Certified by the American Board of Internal Medicine in internal medicine and gastroenterology, he joined the UT Southwestern faculty in 2017. 

Dr. Infante’s research focuses on the molecules and mechanisms that cause cachexia-associated adipose wasting associated with oncologic, liver, infectious, and rheumatologic diseases. By understanding the mechanisms that underlie adipose loss in cachexia, his lab plans to identify new treatments for cachexia patients while also providing insights to induce adipose loss in obesity. He has delivered numerous presentations and published many professional papers, several of which are regarded as classics on the topic of cholesterol transport. 

In 2019, he received a Career Award for Medical Scientists from the Burroughs Wellcome Fund and a research scholar award from the American Gastroenterological Association.
