Dr. Prasad received her PhD in Immunobiology from the University of Cincinnati. Her thesis research explored the crosstalk between the hemostatic and inflammatory systems, focusing on the role of fibrinogen and other hemostatic proteins in Staphylococcus aureus bacterial infection. As a postdoctoral fellow in the Center for Vascular and Inflammatory Disease at the University of Maryland School of Medicine, she examined the precise binding mechanism of a lipoprotein receptor, LRP1, to its inhibitor, RAP, and used this information to develop a more potent inhibitor for LRP1, which has been licensed commercially. Dr. Prasad serves as the Assistant Dean for Research Affairs and the Conflict of Interest Officer for the School of Medicine. In these roles, she is responsible for working with faculty and administrative staff to build the research enterprise at the school.
