Til Stürmer, M.D., M.P.H, Ph.D., is Professor, head of the Pharmacoepidemiology Program, and Director of the Center for Pharmacoepidemiology in the Department of Epidemiology at the University of North Carolina at Chapel Hill Gillings School of Global Public Health. He is also the Director of the Comparative Effectiveness Research (CER) Strategic Initiative, NC TraCS Institute, UNC Clinical and Translational Science Award (CTSA). Dr. Stürmer has a dual focus in epidemiologic methods and clinical epidemiology. His research in epidemiologic methods includes the development of more efficient matching strategies in genetic epidemiology; measurement error correction methods in case-control studies; the value of propensity and disease risk scores for pharmacoepidemiologic studies; the use of validation studies for external control for confounding; and the value of active comparator, new user cohort designs to increase validity of nonexperimental studies of medical interventions. His research in clinical epidemiology covers many topics, including nephro- and cardiovascular toxicity of paracetamol and non-steroidal anti-inflammatory drugs; chemoprevention of colorectal cancer and dementia with non-steroidal anti-inflammatory drugs; determinants of antibiotic resistance; hormone therapy, pain, and sub-clinical inflammation in osteoarthritis; and cardiovascular and cancer outcomes in patients treated with antidiabetics. sturmer@unc.edu; til.sturmer@post.harvard.edu
