Dan is a physician, epidemiologist and tenured Professor of Epidemiology and Medicine. He directs the Center for Innovation in Diagnosis. He was a founding member and Director of the Society for Healthcare Epidemiology of America (SHEA) Research Network, was on the SHEA Board of Directors  and SHEA Chair for IDWeek 2022. At the VA Maryland Healthcare System he directs Epidemiology.

His research explores probability in medicine, medical overuse, diagnostic stewardship, infection prevention and AI. On a NIH New Innovator award for "exceptional scientists pursuing highly innovative approaches to major challenges" he explored clinician risk understanding. This has led to creation of testing wisely

He has continuous federal funding, over 200 publications and his work often appears in the media including the New York Times and Washington Post.
