Background
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.

Landon King Lab
- The Landon King Lab studies aquaporins water-specific membrane channel proteins. We hope to understand how these proteins contribute to water homeostasis in the respiratory tract and how their expression or function may be altered in disease states.
Core Facility
Pulmonary Histology Core
Research Summary
Dr. King’s research focus early in his tenure was the biology of aquaporin water channel proteins in the respiratory tract as well as other tissues. Subsequently, he partnered with others in the division to examine mechanisms contribution the resolution of acute lung injury.
