Research Synopsis

Primarily focused on the measurement of diet in populations and associations with cancer risk, with a particular emphasis on phytoestrogens and breast cancer. Studies have examined dietary assessment methods - including developing and validating food frequency questionnaires, food composition databases, measures of dietary supplement use – and the evaluation of intake, disease risk and dietary interventions.
