Other Positions



Harvard T.H. Chan School of Public Health


Dr. Jun Li is a research scientist in Departments of Nutrition and Epidemiology at Harvard T.H. Chan School of Public Health (HSPH). The main area of her research focuses on the identification of risk factors for prevention of type 2 diabetes (T2D) and cardiovascular disease (CVD), with particular interest and skills on high-dimensional omics research.

Dr. Li is currently leading several projects identifying genomic, metabolomic, dietary, and lifestyle risk factors for T2D and CVD in the Nurses' Health Studies (NHS), Health Professional Follow-up Study, PREDIMED study, Hispanic Community Health Study/Study of Latinos, and the UK Biobank. Her research interests also extend to the new area of systems epidemiology and multi-omics integration. She is adopting new methodologies to integrate multi-omics data (including genetics, epigenetics, metabolomics, and gut microbiome) for the interpretation of disease etiology and identification of mechanisms through which diet/lifestyle factors impact cardiometabolic health.
