Professional Background

Dr. Morrell earned his undergraduate degree from Brown University in 1995. He then graduated from Tufts University School of Veterinary Medicine in 2000 before beginning a comparative pathology fellowship at The Johns Hopkins University School of Medicine. While at Hopkins Dr. Morrell concurrently completed a PhD in the laboratory of Dr. Charles Lowenstein in 2005 where he investigated molecular mechanisms of nitric oxide inhibition of platelet degranulation and received a K08 award. Dr. Morrell then established an \ independent laboratory in the Department of Molecular and Comparative Pathobiology at Hopkins from 2005-2009, before moving to the University of Rochester's Aab Cardiovascular Research Institute. His current research interests include platelets and vascular inflammation.


Research in our lab is focused on the complex interface between platelets, the vasculature, and immune cells. Platelets are not only the cellular mediators of thrombosis, but also have important roles in inflammatory and immune cell responses. Ongoing and past studies by our group have examined platelet, and platelet derived inflammatory mediator interactions with both vascular and immune cells, and the impact of these interactions on tissue injury responses in disease relevant contexts. These studies demonstrated that platelets are regulators of all aspects of inflammatory responses, including the induction of acute phase responses, innate immune cell activation and trafficking, T helper cell differentiation, and B cell development. Our lab regularly uses advanced mouse models to dissect molecular interactions and vascular inflammatory signaling pathways both in vitro and in vivo, establishing our lab as leaders in understanding how platelets regulate vascular and immune cell homeostatic and inflammatory responses. Our work continues to define many novel implications for platelet immune regulation in vascular and inflammatory disease processes.
