Research Interests

My research interests focus on nutrition and the etiology of hormonally-dependent cancers in women (most particularly breast, endometrial, and thyroid cancers). Of particular interest are the effects of phytochemicals that may reduce cancer risk, such as the isoflavones in soy foods, the lignans in whole grains, the isothiocyanates in broccoli and other cruciferous vegetables, and resveratrol in red wine and peanuts. Nutrient-gene interactions are also of interest.
