Expertise and Research Interests

My research program focuses on determining the role of dietary constituents in regulatory mechanisms involved in colon carcinogenesis. We are evaluating the effects of various fiber types, fat sources, and specific phytochemicals contained in them on the tumorigenic process. Aspects of cytokinetics and apoptosis are being measured to determine which of these normal mechanisms are being affected by dietary modifications, and both chemical carcinogens and radiation. Techniques used for these assessments include immunohistochemistry, immunoblotting, real time PCR, and microarray platforms.
