Benjamin Geisler, M.D., M.P.H. is a board-certified internist who practices hospital medicine at Massachusetts General Hospital. He is an international medical graduate from Germany (Charite - Universitaetsmedizin Berlin) and completed a categorical internal medicine residency at NYU School of Medicine in New York City, NY. Prior to clinical training, Ben was a Post-doctoral Research Fellow in decision science at Massachusetts General Hospital and also completed a Master's degree in Public Health at the Harvard T.H. Chan School of Public Health.

As a general medicine doctor, he embraces coordinating clinical care for his patients between the inpatient and outpatient settings and among treating subspecialists. Ben individualizes evidence-based practices, takes patients' preference into account, practices shared medical decision making, and aims to increase the efficiency or value of health care services to provide highly patient- and family-centered care. He is particularly interested in cardiovascular diseases and their prevention, antimicrobial prescribing, rare diseases and diagnostic dilemmas across medical sub-specialties.

Ben is also a health services researcher, decision-analytic modeler, and health economist; he serves as a co-editor of a peer-reviewed journal in those fields, Value in Health. His research had applications across medical conditions although most were in cardiovascular disease. Ben enjoys teaching as well as running quality improvement/patient safety (QI/PS) projects. Recently, Ben has become interested in "big data" and how to use routinely collected health information for research and QI/PS.

Ben's ultimate career goal is to be an active citizen in the academic hospital medicine community.
