I am an Assistant Professor in the Department of Epidemiology, with an affiliation at the Center for Gerontology and Health Care Research (CGHCR). My research focuses on developing and applying novel causal inference methods to inform decision-making for pregnancy and cardiovascular health. Specifically, my work includes emulating target trials to evaluate treatment safety and dietary strategies using large longitudinal data, as well as advancing methods to combine information from multiple data sources to draw valid inferences for target populations of interest.
