Dr. Pozner is an emergency physician at Brigham and Women’s Hospital. He graduated from Tufts School of Medicine and completed residencies in internal medicine at Boston’s Beth Israel Hospital/Harvard Medical School and in emergency medicine at UCLA/Olive View.

Dr. Pozner was the co-founder and founding medical director of the Neil and Elise Wallace STRATUS Center for Medical Simulation at Brigham and Women’s Hospital/Harvard Medical School. Under his leadership, the center has grown from a center exclusively for emergency medicine to serving the entire academic medical center. Skills training and content education is provided to a wide variety of clinicians at all levels. There is a particular emphasis on interprofessional team training. Simulation is also used for quality initiatives at the hospital.

Dr. Pozner’s research interests are in non-technical skills and team training and his primary clinical interest is in resuscitation. He has been an invited speaker nationally and internationally and has been a consultant on simulation projects across the globe. He is the chairperson of the Strategic Relations subcommittee of the Society of Simulation in Healthcare. In 2016, Dr. Pozner received the Bernard Lown Teaching Award, an award to celebrate physicians who are outstanding clinical leaders and recognize the significant role that education plays in the missions of both Harvard and Brigham and Women’s Hospital.

Steven Yule, PhD

Director of Research & Innovation
Fellowship Program Director 
Associate Professor of Surgery, Harvard Medical School

Dr. Yule is a leading academic psychologist with specific expertise and training in organizational psychology, human factors science and mixed methods. He is internationally recognized for his research on assessing non-technical skills and patient safety in surgery. Prior to moving to Boston from Scotland, he developed considerable experience studying team performance and safety in industry sectors as diverse as energy, transportation, and healthcare. Most notably, he was one of the pioneers in developing the ‘Non-Technical Skills for Surgeons’ (NOTSS) behavior observation system, which is now being implemented for surgical education and research in North America, Europe, Australia, Africa and Asia. Dr. Yule is lead author on several seminal papers on the topic and co-founded the Harvard Non-Technical Skills Laboratory, which brings together a multidisciplinary group of scientists who are passionate about studying the impact of non-technical skills on process measures and patient outcomes, as well as implementing scalable interventions to enhance patient safety. Simulation is core to this mission and at STRATUS, Dr. Yule ensures that the curricula are rigorously developed and reviewed to provide the most immersive and beneficial experience for learners. He represents STRATUS nationally in his roles as vice-chair of the American College of Surgeons (ACS) committee on non-technical skills, and co-chair of the Association for Academic Surgery (AAS) Education committee.
