Director of the Gastroenterology Metabolic and Bariatric Program
PLEASE NOTE: I see patients for weight loss related clinic visits at the Anschutz Health and Wellness Center.
Research Interests
My research interest focus on treating obesity and obesity related diseases. I have been an investigator on seven FDA trials for endoscopic weight loss devices and procedures. I also study the metabolic effects of diet and exercise on nonalcoholic fatty liver disease.
