  • My research focuses on the measurement of diet in populations and its association with cancer risk, with a particular emphasis on phytoestrogens and breast cancer. We have conducted studies examining dietary assessment methods and nutrient databases, including developing and validating food frequency questionnaires, assessing dietary supplement use, and the effectiveness of dietary interventions.
