Dr. Chanmugam joined the faculty in 1992 and served as the residency director for the Emergency Medicine Residency Program from 2000 to 2010.

He is associate editor for the 4th edition of the textbook Clinical Procedures in Emergency Medicine and is a regular contributor and administrative editor for Practical Reviews in Emergency Medicine, a monthly publication.

His primary interest is medical education. In 1994, he developed and introduced the required clerkship in emergency medicine, making it the first time that Johns Hopkins medical students were required to have exposure to EM. He has also participated in the development of a novel program - masters in medical education and has been the recipient of multiple teaching awards.

Outside of Hopkins, he is on the Board of Directors for Maryland ACEP and serves as the vice chair for the Governor’s Council on Heart Disease and Stroke. He is an avid outdoor enthusiast and is an instructor in the martial art Aikido. more
