About

Xiao Ou Shu is a leading epidemiologist whose research has fundamentally shaped our understanding of the environmental and genetic determinants of cancer. Her key research areas encompass cancer epidemiology, molecular epidemiology, and the interplay between lifestyle factors and genetic susceptibility. A major contribution is her pioneering work on the Shanghai Women’s Health Study, a landmark prospective cohort that has yielded critical insights into how diet, physical activity, and hormone-related factors influence breast cancer risk. Her impact is profound, with her most-cited papers collectively amassing tens of thousands of citations, reflecting her role in establishing foundational knowledge on gene-environment interactions and cancer prevention. Notably, she has been instrumental in elucidating the role of folate metabolism and one-carbon metabolism in carcinogenesis, and her studies on the effects of obesity and physical activity on cancer survival have guided public health recommendations. A highly decorated researcher, Shu’s work has been recognized with numerous awards, and she continues to mentor a new generation of epidemiologists, ensuring her legacy of rigorous, impactful science endures.
