Ethan Weiss, MD

Assoc Prof In Res

CLINICAL INTERESTS: Dr. Ethan Weiss is a cardiologist specializing in general cardiology. His special interests include preventive cardiology, genetics of coronary disease, risk assessment, and heart disease in the young.

RESEARCH INTERESTS: In his research, Dr. Weiss uses genetic models to better understand the mechanism of metabolic disorders such as obesity, fatty liver disease, and diabetes. He also studies the blood clotting system and has interest in identifying novel ways to safely block clots associated with diseases such as heart attack and stroke without causing an increase in bleeding.
