He began his research funding with a KO7 Career Development Award from NCI focused on practice transformation in the 1990’s. He has had a series of RO1’s focused on colorectal cancer prevention. His research team demonstrated that a single daily dose of aspirin could have long term biological changes in the colon tissue that explained the observational data of aspiring protecting one from colorectal cancer.

His current research is focused in stool microbiome as a new early detection biomarker for colorectal cancer.
