Roger Daglius Dias Biography

Roger Daglius Dias is a physician-scientist and entrepreneur whose career integrates medicine, artificial intelligence, and human performance. Dias holds an M.D., Ph.D. in medical sciences, and an M.B.A. He trained in internal medicine and emergency medicine at University of São Paulo Medical School, followed by a postdoctoral research fellowship at Harvard Medical School, where his focus included simulation, human factors, wearable sensors, and machine learning. Dias serves as associate professor of emergency medicine at Harvard Medical School and as director of research and innovation at the STRATUS Center for Medical Simulation at Brigham and Women's Hospital, where he leads the Medical AI & Cognitive Engineering Lab.

Dias's research applies artificial intelligence, machine learning, and digital biomarkers to assess and enhance clinician performance and improve patient safety in emergency medicine, critical care, surgery, space medicine, and military medicine. His scholarly work includes publications such as "Using Machine Learning to Assess Physician Competence: A Systematic Review" in Academic Medicine and "Computer Vision in the Operating Room: Opportunities and Caveats" in IEEE Transactions on Medical Robotics and Bionics. His lab has advanced research in augmented reality for trauma care and AI-based decision support for surgical teams, with investigations supported by the National Institutes of Health.

In addition to his academic roles, Dias co-founded Xtory, a medical AI company focused on clinical decision support, where he serves as CEO. Xtory uses generative AI to provide clinicians with real-time insights from patient data, supporting accurate and timely clinical decisions. This work aligns with his research on biomarkers of stress among emergency room physicians and his commitment to understanding clinician performance in high-risk environments.
