Dr. McElroy is a pediatric infectious disease physician with a research interest in hemorrhagic fever viruses. She holds an appointment as Assistant Professor in the School of Medicine at the University of Pittsburgh. She provides clinical care at UPMC Children's Hospital of Pittsburgh. Her lab focuses on the mechanisms by which hemorrhagic fever viruses cause disease.

We study the interactions that occur between the host immune system and emerging viral pathogens. To do this, animal model systems, clinical specimens from cases of human disease, and in vitro models are used. Previous work has focused on the Hantaviruses, Rift Valley fever virus (RVFV), Crimean-Congo hemorrhagic fever virus, Ebola virus and Lassa virus. Current studies are utilizing the mouse model to elucidate the role of T cells in immunity to RVFV.
