Elizabeth Diemer is a faculty member in the Department of Pediatrics at Children’s Hospital of Philadelphia and an assistant professor of epidemiology in the Department of Biostatistics, Epidemiology, and Informatics at the Perelman School of Medicine at the University of Pennsylvania. Her research focuses on applying and improving causal inference methods to improve the safety and efficacy of treatment and prevention strategies for pediatric illnesses. She is especially interested in applying these methods to improve care for children with psychiatric illnesses, where randomized trials are often infeasible.

Much of her previous methodologic work has focused on addressing limitations of instrumental variable methods. This has included evaluating common sources of selection bias, refining existing bias identification approaches, and applying novel partial identification strategies using data from the Norwegian Mother, Father, and Child Study (MoBa), the Million Veteran Program, and Generation R. In addition, she has collaborated broadly on projects related to causal inference and target trial emulation in perinatal, psychiatric, and cardiovascular epidemiology.
