Dr. Du’s research aims to identify genetic and modifiable predictors of colorectal and endometrial cancers, with the goal of better understanding tumorigenesis and informing improved preventive strategies. She is an active investigator in the Genetics and Epidemiology of Colorectal Cancer Consortium, a large collaborative effort including over 40,000 participants. Together with researchers from North America, Australia, and Europe, she studies the interplay of genes and environment (e.g., anthropometrics, lifestyle, diet, and medication use) in colorectal cancer. She is also active in the Epidemiology of Endometrial Cancer Consortium, a collaborative effort including over 45 population-based studies, where she and colleagues are studying diabetes, obesity, and hypertension in the development of endometrial cancer. In addition to her consortia work, Dr. Du studies telomere dynamics and their role in cancer in the Nurses’ Health Study, a large nationwide cohort of women’s health. She is also collaborating with MSK colleagues in the Global Cancer Disparity Initiatives program to form a hospital-based case-control study investigating cancer determinants in sub-Saharan Africa.
