He specializes in the care of patients with gastrointestinal cancers and runs an independent laboratory at the Dana-Farber Cancer Institute focused on the biology of pancreatic cancer.

He received his medical and graduate degrees as part of the Tri-Institutional Weill Cornell/Rockefeller/Sloan-Kettering M.D.-Ph.D. Program earning a Ph.D. degree from the Weill Cornell Graduate School of Medical Sciences and his M.D. from Weill Cornell Medical College.
