Dr. Fang Fang Zhang is a cancer epidemiologist with experience in conducting population-based studies to investigate the role of nutrition in cancer prevention and control. She is Chair of the Division of Nutrition Epidemiology and Data Science at the Friedman School of Nutrition Science and Policy at Tufts University.


The optimal strategies to improve diet and reduce cancer are not clear. While various individual-level behavior change approaches can be effective for some people, overall benefits and long-term adherence may be modest and overall benefits poorly sustained. In contrast, population strategies can be more powerful and achieve broader impact. Supported by NIH, Dr. Zhang is leading a multidisciplinary R01 project to evaluate the effectiveness, cost, and cost-effectiveness of population-based dietary interventions at the national level on cancer outcomes in the US.
