Dr. Homan completed his fellowship in Cardiovascular Disease at NewYork-Presbyterian/Cornell, where he served as Chief Cardiology Fellow and undertook an additional year of laboratory training in cardiometabolic biology with Dr. James Lo. He completed his Internal Medicine residency at NewYork-Presbyterian/Columbia, before which he received his M.D. degree from the Icahn School of Medicine at Mount Sinai. Prior to medical school he earned a Ph.D. in Chemistry from Harvard University and received his B.S. degree in Chemistry from the University of Florida in Gainesville.

Dr. Homan's research has focused on understanding the relationship between obesity and cardiovascular disease. During his cardiology fellowship at Weill Cornell, he studied the role of the innate immune system in obesity-related liver disease and heart failure, and he received the Glorney-Raisbeck Fellowship Award in Cardiovascular Disease. In his PhD research at Harvard University, he discovered a new class of endogenous lipid molecules that he named fatty acyl hydroxy fatty acids (FAHFAs), which were ultimately found to have anti-diabetic and anti-inflammatory properties.

Dr. Homan is a member of the American College of Cardiology, the National Lipid Association, and the American Society of Echocardiography. He also speaks Spanish and French.
