Dr. David C. Landy is a clinical fellow in arthroplasty at the Hospital for Special Surgery. He has an interest in the conduct of clinical research within orthopedics and the efficient alignment of methods with purpose. After completing an undergraduate degree in philosophy at Vanderbilt and a master’s degree in public health at Dartmouth, he worked as a statistician in empirical bioethics at Baylor College of Medicine helping to study the ethics of various clinical research methodologies. Following this, he completed the medical scientist training program at the University of Miami where he studied the application of advanced statistical methods to the analysis of imbalanced cohort data and worked with various large datasets. Dr. Landy is a member of the American College of Epidemiology, has published over 50 peer reviewed articles, has received independent research support from the American Federation for Aging Research and American Heart Association, and has served as a reviewer for 16 different peer-reviewed journals publishing ethics and epidemiological research.

Dharmesh Vyas, MD, PhD
University of Pittsburgh Medical Center
Medical Director and Head Team Physician, Pittsburgh Penguins Hockey Team
Dharmesh Vyas, MD, PhD is an associate professor of orthopaedic surgery at the University of Pittsburgh Medical Center (UPMC). He also serves as the Medical Director and Head Team Physician of the Pittsburgh Penguins Hockey Team. After completion of his orthopaedic residency at the University of Chicago, Dr. Vyas did his sports medicine and shoulder surgery fellowship at the University of Pittsburgh. During that time, he also trained at the Rechts der Isar in Munich, Germany and the Albert Trillat Hospital in Lyon, France. Dr. Vyas is actively involved in the resident and sports medicine fellowship programs at UPMC. His clinical interests are sports medicine and arthroscopy of the shoulder, knee, and hip. Special interests include ACL reconstruction, knee cartilage restoration, shoulder instability in athletes, and treatment of hip femoroacetabular impingement. His research interests are focused on improving our understanding of shoulder instability, and on bench research aimed at elucidating the molecular mechanisms responsible for improved rotator cuff healing.
Dr. Vyas has published several peer-reviewed articles and several book chapters. His research goals are centered on understanding soft tissue to bone healing at the molecular level and in the process translate this science to improving clinical outcomes after sports medicine procedures. This foundation for his interest in this field was built upon his PhD work which was focused on understand the cellular and molecular basis of skeletal muscle and bone adaptation to load. For his work, he has lectured both nationally and internationally and mentored several residents and fellows who have entered academic practice.
Dr. Vyas is a Diplomate of the American Board of Orthopedic Surgery, an active member of the American Orthopedic Society for Sports Medicine (AOSSM), Arthroscopy Association of North America (AANA), American Shoulder and Elbow Society (ASES), and the NHL team physician’s society (NHLTPS). Dr. Vyas is an avid soccer player and golfer but enjoys most spending his days with his wife Avni and their two daughters Maya and Arya.
