Biosketch

Stephen Rogers (PhD.) is Assistant Professor in the Department of Pediatrics at the University of Maryland School of Medicine and works at the Center for Blood Oxygen Transport and Hemostasis. He is an exercise physiologist by training, with specific interest in red blood cell (RBC) physiology and pathophysiology.

His research focus is on signaling and interplay between RBCs and the vasculature; more specifically, the role of RBCs regulating regional blood flow (i.e., matching oxygen delivery to metabolic demand) and maintaining cardiovascular homeostasis (i.e., dealing with vascular reactive oxygen species [ROS] via metabolic maintenance of antioxidant capacity). His work ultimately considers how RBCs adapt to or sustain injury under various conditions (i.e., blood storage, diabetes, sickle cell disease, sepsis, anemia), how this influences RBC physiologic performance, and plays into the amplification of disease (or related morbidity) progression.

Research/Clinical Keywords

Red blood cells, nitric oxide, s-nitrosothiols, SNO, SNO proteins, hemoglobin, diabetes, sepsis, sickle cell, blood storage, anemia
