Daniel Morgan MD, MS is a physician and epidemiologist in Baltimore, Maryland. He is Associate Professor of Epidemiology and Medicine at the University of Maryland School of Medicine, Chief Hospital Epidemiologist at the Baltimore VAMC and a fellow at the Center for Disease Dynamics, Economics and Policy (CDDEP). His research explores infection prevention and medical overuse. This includes pragmatic issues related to the control of infectious diseases in the hospital and patient safety, including the best use of patient isolation, automated methods for hand hygiene compliance, prevention of MRSA and carbapenem-resistant Enterobacteriaceae (CRE), the importance of the environment on transmission of bacteria, multicenter infection prevention studies and antimicrobial stewardship. He was a founding member and past Director of the Society for Healthcare Epidemiology of America (SHEA) Research Network and on the Board of Directors of SHEA. He is a visiting fellow with Ramanan Laxminarayan and CDDEP where he works on international issues of antimicrobial use. His research on overuse has focused on overuse of general medical care, the harms of syncope, physician understanding testing and treatment effects and a Research Agenda on medical overuse with the Lown institute where he co-chaired the annual Research meeting from 2014-2016. On a NIH New Innovator award for "exceptional scientists pursing highly innovative approaches to major challenges" he is exploring how poor clinician risk understanding leads to overuse.

His work is funded through the National Institutes of Health (NIH), Department of Veterans Affairs, the Centers for Disease Control and Prevention (CDC), the and the Agency for Healthcare Quality and Research (AHRQ). His research has been published in JAMA, the BMJ, JAMA Internal Medicine and Clinical Infectious Diseases and has been featured in the New York Times, The Incidental Economist, US News & World Report, Consumer Reports, the Baltimore Sun, the Los Angeles Times and NPR.
