His major research focus is in the prevention of type 2 diabetes. His research projects on the role of vitamin D on cardiometabolic disease are as follows:

1. Vitamin D and Calcium Supplementation for Prevention of Type 2 Diabetes (CADDM study, www.caddm.org). This is a randomized controlled trial of vitamin D and calcium supplementation in participants with glucose intolerance at baseline. Primary outcome is change in Disposition Index, measured by the IVGTT.  Supported by NIDDK (R01, PI Pittas)
2. Vitamin D and Incident Type 2 Diabetes. This is a case-control study nested within the Nurses Health Study to examine the association between plasma 25-hydroxyvitmain D and incident type 2 diabetes. Supported by NIDDK (R21, PI Pittas)
3. Vitamin D and Cardiometabolic Disease. This is an observational study within the DPP/OS study to examine the association between 25-hydroxyvitamin D and incident type 2 diabetes and cardiovascular disease. Supported by NIDDK (R01, PI Pittas)
4. Vitamin D Supplementation for Prevention of Type 2 Diabetes in African-Americans. This is a randomized controlled trial of vitamin D supplementation in African-Americans with glucose intolerance at baseline. Supported by American Diabetes Association (PI Harris)
