Why I Became a Scientist

I became a scientist because it was clear during my training as a physician that many treatment decisions are made on the basis of poor or little evidence and that a great need exists to apply the principles of epidemiology to clinical care.  I was fortunate to start my career at a time when the "evidence-based" medicine movement was gaining momentum, and have greatly enjoyed designing and implementing large scale clinical trials that answer questions that have direct implications for patient care. 

Research Summary

Our group is currently conducting more than 30 randomized controlled trials evaluating new treatments for Crohn's disease, ulcerative colitis and Type I diabetes mellitus.
