Srinivasa N. Raja, MD, is professor in the department of Anesthesiology/Critical Care Medicine, and director of Pain Research and the Division of Pain Medicine at the Johns Hopkins University School of Medicine.

Dr. Raja is Professor of Anesthesiology and Neurology, and Director of the Division of Pain Medicine in the Department of Anesthesiology and Critical Care Medicine at the Johns Hopkins University School of Medicine in Baltimore USA. He received his early medical training in India, his residency training in Anesthesiology at the University of Washington, Seattle, and post-doctoral training at the University Of Virginia School Of Medicine. He was awarded the Diplomate of the American Board of Anesthesiology in 1982, and added Qualifications in Pain Management in 1993 and was recertified in 2002. 

Clinical interests of Dr. Raja’s include management of chronic pain states, such as complex regional pain syndromes, sympathetically maintained pain, postherpetic neuralgia, and post-amputation pain. His recent research efforts are aimed at understanding the peripheral and central mechanisms of neuropathic pain and in determining the role of opioid and adrenergic receptor mechanisms in mediating or maintaining chronic neuropathic pain states. His lab is also involved in studies to determine the mechanisms of actions of spinal cord stimulation for chronic pain. He has also conducted controlled clinical trials to develop better evidence-based practices for the pharmacological treatment of neuropathic pain.

Dr. Raja served as an Editor of Anesthesiology from 1998-2006. He established the section “Classic Papers Revisited” in 2000, and served as the Section Editor. He is presently a Section Editor (Clinical:Science, Epidemiology and Clinical Notes) for the journal Pain. Dr. Raja is the Chair of the Scientific Advisory Committee for the 15th World Congress on Pain, 2014 in Buenos Aires. He is the vice-Chair for the Neuropathic Pain Special Interest Group, IASP.

Dr. Raja and his collaborators have published more than 170 articles in peer-reviewed journals such as: Anesthesia and Analgesia, Anesthesiology, Brain, J. of Neurophysiology, J. of Neuroscience, Nature, Neurology, Pain, and Science. He is an Editor of four books and has written numerous book chapters. He has been invited to lecture both nationally and internationally, and has been invited as a Visiting Professor to several universities. His awards include the 14th annual Benjamin G. Covino lecture at Harvard University, the Wilbert E. Fordyce Clinical Investigator Award, the American Pain Society, 2008 and the John J. Bonic award from ASRA, 2010.
