Dr. Anastassios Pittas was born and raised in Greece and came to the U.S. many years ago to attend college. At MIT, not only did he earn a B.S. degree in Biology, but also met his future spouse, Helen. Both earned their medical degrees at Weill Medical College of Cornell University and completed Internal Medicine Residencies at the New-York Presbyterian Hospital-Weill Cornell in New York City before moving to Boston. Following a Fellowship in Endocrinology at Tufts Medical Center, Dr. Pittas joined the staff in the Division of Endocrinology in 2000.
From 2000 and 2002, Dr. Pittas was supported by a generous grant from the Friedman NY Foundation for Medical Research. In 2002, he was fortunate to become the recipient of a National Institutes of Health K23 Career Development Award to focus on diabetes research. During this period, in keeping with the goal of the Award, he earned a M.S. degree in Clinical Research from the Sackler School of Biomedical Sciences at Tufts University. The degree provided him with formal training on clinical research and during that time, he became interested in the role of vitamin D in diabetes. Working with wonderful colleagues, he received NIH funding (R21 and R01 mechanisms) to further test the idea and ultimately led the D2d study (www.d2dstudy.org), a multi-center clinical trial to test the safety and efficacy of vitamin D supplementation in reducing risk of diabetes in people at high risk.
Dr. Pittas is a Professor of Medicine at Tufts University School of Medicine and Adjunct Professor of Nutrition and Policy at Tufts University Friedman School of Nutrition, Science and Policy. He also serves as the Associate Director of the Endocrinology Fellowship Program at Tufts Medical Center.
