About

Bio

I majored in Biology at Harvard University. While in college, I did research in Vitamin D metabolism at the Mass General. I then went to Washington University for medical school. After completing a fellowship in Gastroenterology and Hepatology at Northwestern, I decided to move to New York. After 3 years in an academic practice with Columbia where I did probiotic research, I decided to go into private practice. I currently practice in New York City and am affiliated with NYU Medical Center.
