Research Interests:

In 1996 I started working to identify compounds in the diet that were capable of mediating the initiation, promotion and progression of colon cancer.  Most of the work has addressed the role of dietary fiber and the bioactive molecules in fiber-containing foods on mitigation of various aspects of colon carcinogenesis and inflammatory bowel disease.  Current research is designed to understand how bioactive compounds influence the intestinal environment, with particular attention to the interaction between the microbiota and the colon epithelia.  Efforts are focused on understanding the regulators of signaling between microbiota and epithelial cells through toll-like receptors and their down-stream effects on the regulation of expression of inflammatory mediators.  Disease initiators/promoters used in our studies have included chemical carcinogens, galactic cosmic radiation (Brookhaven National Laboratory), and pro-inflammatory agents.  The research has produced 54 peer-reviewed papers and book chapters, and one co-edited book entitled “Potential Health Benefits of Citrus”.
