Hamblin is a writer and senior editor at The Atlantic magazine, where he hosts the video series If Our Bodies Could Talk, for which he was a finalist in the 2015 Webby awards for Best Web Personality. He is the recipient of a 2015 Yale University Poynter Fellowship in journalism. His work has been featured in/on The New York Times, Politico magazine, NPR, BBC, MSNBC, New York, The Awl, and even mentioned in passing on The Colbert Report. Time named him among the 140 people to follow on Twitter in 2014, Greatist named him among the most influential people in health media in 2015, Refinery29 listed him as a "Man to Watch" in 2015, and BuzzFeed called him "the most delightful MD ever," though he is not as delightful as William Carlos Williams.
After medical school Hamblin did three years of medical residency before joining The Atlantic to develop a health section and, at least for now, work entirely in media. More on that at Columbia Journalism Review, Journal of the American College of Radiology, and Capital New York.
