Personal Statement

My research focuses on the epidemiology and pathogenesis of complication development in type 1 diabetes through applying various analytic methods which are under-used in epidemiology, such as regression trees, accelerated failure time models, and joint modeling, to address limitations of more traditional statistical approaches. I am particularly interested in utilizing longitudinal data to investigate factors that may contribute to the earlier identification of risk for cardiovascular and renal complications. Most of this work has focused on data from the Epidemiology of Diabetes Complications Study (EDC), a longitudinal prospective cohort study of type 1 diabetes, which has been followed for over 30 years. Currently, I am the PI of an American Diabetes Association Junior Faculty Development Award project entitled Epigenetics of Glycemic Exposure and Complication Development in Type 1 Diabetes, the goal of which is to examine whether differential DNA methylation improves prediction of type 1 diabetes complications over what is already predicted by long-term blood sugar control. Additionally, I have extensive experience planning and executing statistical analyses of studies in lifestyle modification research. I have served as a statistician on several community-based translational/effectiveness trials, including Physical Activity and Sedentary Behavior Change; Impact on Lifestyle Intervention Effects for Diabetes Translation and Diabetes Prevention Translation Project - The healthy LIFESTYLE Program.
