S. Ryan Greysen, MD, MHS, MA has been the Section Chief of Hospital Medicine in Penn's Division of General Internal Medicine since August 2016. A native Texan, Dr. Greysen received both his BA and MD with Honors from the University of Texas. He completed residency training in Internal Medicine (Primary Care) at George Washington University, graduate study in History and Sociology of Science at Penn (MA ‘03), and post-doctoral training at Yale (MHS) as a Robert Wood Johnson Clinical Scholar. Before coming to Penn, he was an Assistant Professor at the University of California, San Francisco (UCSF) in the Division of Hospital Medicine. Dr. Greysen’s quality, safety, and research efforts focus on improving hospital and transition care for vulnerable patients, particularly older adults with multiple morbidities. He launched the first ACE program at UCSF Medical Center and obtained extramural funding from the NIH National Institute on Aging as well as significant intramural funding to study patient-centered stressors such as poor functional status, mobility, sleep, and engagement in care (see www.arches-cohort.org). He is also keenly interested in the potential for personalized mobile technologies to help alleviate these stressors and increase patient and caregiver engagement in acute and recovery care. Dr. Greysen’s research has been published in leading journals including JAMA, JAMA Internal Medicine, Annals of Internal Medicine, Journal of General Internal Medicine, and Journal of Hospital Medicine and has been covered by the New York Times, Washington Post, and National Public Radio. He is the first recipient of the Junior Investigator Award from the Society of Hospital Medicine in 2015 as well as the first hospitalist to be awarded the Outstanding Junior Investigator Award by the Society of General Internal Medicine and the American Geriatrics Society, both in 2016. As Section Chief for Hospital Medicine at Penn, Dr. Greysen leads the development of a scalable model for academic hospital medicine across all sites within Penn Medicine that will engage all faculty in clinical, educational, quality, safety, and research excellence. The Section currently maintains a core faculty of 35 hospitalists who provide care at HUP, Penn Presbyterian Medical Center, Philadelphia VAMC, and Good Sheppard Penn Partners and who play critical roles in quality, safety, education in the Perelman School of Medicine and University of Pennsylvania Health System.
