Research Profile

Research Interests

The role of nutrition in development and progression of cancer

  • The effects of dietary components on signaling in premalignant pancreatic lesions
  • Mechanisms leading to progression from PanINs to pancreatic ductal adenocarcinoma

Lab Overview

Pancreatic cancer is the 4th leading cause of cancer deaths in the US with a 5-year survival rate of less than 7% and a median survival of only 3 to 6 months. The majority of pancreatic ductal adenocarcinomas are diagnosed at a late stage, are not surgically resectable, and respond poorly to chemotherapy, so an emphasis on earlier detection methods is critical. Several groups have reported a possible link between diet and the development of pancreatic cancer, but any potential mechanism has yet to be determined. Our lab is interested in elucidating the role of dietary components that affect signaling events that promote the development of pancreatic cancer.
