Pulmonary and Critical Care Medicine


As Executive Vice Dean for the Johns Hopkins University School of Medicine, Dr. King oversees research administration, policy coordination, and the identification and coordination of technology transfer opportunities. He assists in overseeing operations and program development in the School of Medicine.

Dr. King received his medical degree in 1989 from Vanderbilt University and first came to Hopkins that year as an intern in the Osler Medical Service. As a postdoctoral fellow and later, after joining the faculty as an assistant professor in 1997, he undertook important studies of water channels in the lung with 2003 Nobel Laureate Peter Agre. In 2005, he was selected to be the Director of the Division of Pulmonary and Critical Care Medicine. He was elected to the American Society for Clinical Investigation in 2006 for work on aquaporin water channels. His work currently focuses on mechanisms regulating repair of lung injury. more
