About Sudarshan Rajagopal
"Dr. Sudarshan Rajagopal is a physician-scientist and is currently an Associate Professor of Medicine and Biochemistry at Duke University School of Medicine. He obtained his B.S. in Chemistry from The University of Chicago in 1998 and subsequently enrolled in the Medical Scientist Training Program at The University of Chicago. During his doctoral work in the lab of Prof. Keith Moffat, he studied the structural mechanisms of bacterial photoreceptors using time-resolved Laue crystallography. He was awarded his PhD in 2004 and his MD in 2006. He then joined the Internal Medicine Residency training program at Duke University Medical Center. During his Cardiology fellowship, he trained in the lab of Dr. Robert J. Lefkowitz, where his research focused on biased agonism, with the development of approaches to quantify ligand bias and the identification of ACKR3 as an endogenously beta-arrestin-biased receptor.
After completing his training, he joined the faculty at Duke, with a focus on the mechanisms underlying biased agonism at GPCRs and its contribution inflammation and cardiovascular disease. His group and others have shown that many of these ligands act as biased agonists for the same receptor. His lab is also interested in identifying novel signal transduction mechanisms of GPCRs, such as the formation of complexes between G proteins and beta-arrestins. His clinical focus is on pulmonary arterial hypertension, a disease of the pulmonary arterioles that causes right heart failure, and he serves as co-director of the Duke Pulmonary Vascular Disease Center."
