Tina Costacou, PhD

Dr. Costacou is a nutrition and diabetes epidemiologist, whose research interest has mainly focused on the effects of potentially modifiable environmental (e.g. nutrition, obesity) factors and their genetic interactions on diabetes complication development.  She started her career providing support for the Nutrition Coordinating Center of the DPP clinical trial and has since worked on large multi-center studies in the U.S. (IRAS, EDC) as well as in Europe (EPIC).  She has published extensively on factors leading to the development of diabetes complications and has focused on gender interactions.  Currently, Dr. Costacou is PI of an R01 on the role of HDL in coronary artery disease and regional PI of a DP3 assessing the role of ApoC3 and HDL function on cardiovascular complications of type 1 diabetes.  She is also Co-Investigator in the Pittsburgh Epidemiology of Diabetes Complications (EDC) study, a randomized clinical trial comparing two screening methods for gestational diabetes (G2DM)
and on a study aiming to develop and validate models to predict the long-term health and economic outcomes of interventions for type 1 diabetes.
