Greg A. Merrell, MD received his medical degree from Yale University. He continued at Yale for his orthopaedic residency. Dr. Merrell received his fellowship training in upper extremity and microvascular surgery from Brown University.

Dr. Merrell has special interests in wrist arthritis, fracture care, minimally invasive surgery of the elbow and wrist, as well as conditions of the shoulder. He has authored numerous scientific publications and book chapters on the minimally invasive treatment of fractures. Dr. Merrell has an active research program established.

Dr. Merrell is an Associate Editor for the Journal of Hand Surgery, and a member of the clinical trials and outcomes committee for the American Society for Surgery of the Hand.

His research interests include the study of bone healing. Dr. Merrell won the Marshall Urist American Orthopaedic Association award for his research on bone healing. He has written a number of journal articles and book chapters on minimally invasive treatment of scaphoid fractures. He was the invited author from the Journal of Hand Surgery to describe his minimally invasive surgery for the treatment of tennis elbow. Dr. Merrell served as team physician for the 2002 Search for Genghis Khan Expedition to Mongolia. This expedition was featured on a Discovery Channel documentary.
