Research Focus


My research focuses on research methods for epidemiologic research. Many statistical tools were not designed to address challenges of modern epidemiology. We would like to infer causation in complex problems, and we deal regularly with "big data" (large administrative databases of health care utilization). Traditional statistical methods can give biased results in these situations. My team develops methods to address these problems, and implements and evaluates these new methods in research problems in perinatal epidemiology and in drug safety.
