Research Focus

My research interest is in big data and health informatics. My primary focus is developing algorithms which optimize data analysis and predictive modeling using electronic health records (EHR). One project examines the association of antibiotics and hemoglobin A1c (HbA1c) with mortality. Another project concerns diabetes, obesity and the discordance between county-level diabetes and obesity prevalence among veterans. I am also developing tools which can predict short- and long-term risk of mortality. My other research interests include examining outcomes associated with Clostridium difficile infection and developing a decision support tool for early identification of Alzheimer’s disease in a pre-clinical stage.
