I have been Chief of Gastrointestinal Surgery and Professor of Oncology at Roswell Park Cancer Institute since April 2012. I did my residency at the NYU Medical Center Department of Surgery and both research and clinical fellowships at Memorial Sloan Kettering Cancer Center and I am a graduate of Johns Hopkins University with a MD from New York University School of Medicine.

My research focuses on technical advances in minimally invasive esophageal and GI surgeries and developing new targets and agents for treatment of pancreatic and other GI cancers. I lead a funded laboratory program which focuses on glucose promotion of histidine signaling to drive cancer progression in the absence of growth factor stimulation. The goal is to target histidine signaling as novel therapy in GI cancer.
