Dr. Gwen Murphy earned a Ph.D. in clinical medicine from Trinity College, Dublin, Ireland in 2005, and an M.P.H. from University College, Dublin in 2006. She joined DCEG as an NCI Cancer Prevention Fellow in the Infections and Immunoepidemiology Branch in 2006, where she worked with Charles Rabkin, Ph.D., to initiate the NCI International Epstein-Barr virus (EBV)-Gastric Cancer Consortium. During her fellowship, she also collaborated with Dr. Amanda Cross on a series of molecular epidemiology studies within the Polyp Prevention Trial. In 2009, Dr. Murphy moved to the Nutritional Epidemiology Branch as a research fellow, becoming a staff scientist in 2012.

Research Interests

Dr. Murphy’s research explores the role of hormones produced within the gastrointestinal tract in the etiology of gastrointestinal cancers. She also investigates the role of Helicobacter pylori infection and its sequelae in relation to gastric and other cancers. In recognition of her research, Dr. Murphy has received a Cancer Prevention Research Training Merit Award, a Fellows Award for Research Excellence, an Intramural Research Award, and in 2012 an award for Outstanding Research Paper by a DCEG Fellow. She currently chairs the Upper Gastrointestinal Cancer Research Group at DCEG and sits on the DCEG Tech Transfer Committee.

In the Metabolic Epidemiology Branch, Dr. Murphy coordinates a number of large field studies of upper gastrointestinal cancers in high-incidence areas (China, Iran, Kenya, Brazil) and continues to coordinate the Polyp Prevention Trial.

Dr. Murphy is a member of the African Esophageal Cancer Consortium (AfrECC).
