Dr. Song’s primary research area is the primary prevention and epidemiology of type 2 diabetes and cardiovascular disease.

His major research interests include:

  • Relation of nutritional, biochemical and genetic markers of dietary factors with type 2 diabetes and cardiovascular disease
  • Racial/ethnic differences in vitamin D-related biomarkers and racial/ethnic disparities in cardiovascular disease risk
  • Design and conduct of randomized controlled trials of dietary supplements for primary prevention of type 2 diabetes
  • Pharmacoepidemiology research on comparative effectiveness and safety of a novel antidiabetic drug, sodium–glucose cotransporter 2 (SGLT2) inhibitors
  • Design and conduct of systematic review and network and pairwise meta-analysis for synthesizing evidence from observational and randomized trial data

Dr. Song has a broad background in medicine, nutrition, genetics, and epidemiology and has extensive experience in the evaluation of nutritional, biochemical, and genetic markers as predictors of type 2 diabetes and cardiovascular disease (CVD) in several large prospective cohort studies, such as the Women’s Health Study (WHS), Physicians’ Health Study (PHS), and the Women’s Health Initiative-Observational Study (WHI-OS). He has also been actively involved in testing the role of several dietary supplements in preventing type 2 diabetes in multiple large-scale randomized, double-blinded, placebo-controlled trials, including the Women’s Health Study, the Women’s Antioxidant Cardiovascular Study (WACS), the Physicians’ Health Study (PHS) II randomized trial, and the VITamin D and OmegA-3 TriaL (VITAL).
