Internal Medicine (Ireland)

I am a medical oncologist whose research and clinical activities focus on treating pancreatic and hepatobiliary cancers. I work very closely with a team of surgeons, oncologists, and radiation therapists to determine and provide the best treatment for people with these diseases.

Read more

My research initiatives include integrating molecular and genetic-based therapies into the treatment of pancreas cancer, developing adjuvant and neoadjuvant therapies, and identifying biomarkers that may be used to select therapy. I am the principal investigator of multiple phase I, II, and III pancreatic cancer clinical trials and have authored and co-authored more than 300 articles, editorials, and book chapters.

In addition to caring for patients at MSK and conducting research, I am Chair of the Human Research Protection Program, the Institutional Review and Privacy Board, and the Continuing Medical Education Committee. I also teach and mentor national and international oncology fellows, junior faculty, residents, and house staff and have received numerous teaching awards.

Outside of MSK, I collaborate with groups and experts around the world to improve outcomes for people with pancreas and hepatobiliary cancers. Nationally, I am Co-Chair of the NCI Alliance Co-Operative Group Gastrointestinal Cancers Committee and a member of the NCI Gastrointestinal Cancers Steering Committee. I also serve on the medical and scientific advisory board of the Pancreatic Cancer Action Network, National Comprehensive Cancer Network Pancreas panel, American Society of Clinical Oncology Guidelines Committee, and the scientific board of the National Pancreas Foundation. I received my medical degree from Trinity College at Dublin University in Ireland, where I was born.
