Overview
My career has primarily focused on clinical care of hip and knee arthritis. I run a busy Adult Reconstruction (hip and knee replacement) practice. I am also Chief of the Orthopedic Surgery service at the Durham VA medical center. In these roles, I work daily with orthopedic residents, and train them to manage these issues both non-operatively and with surgery. I also mentor residents, fellows,and medical students on their research projects, typically in collaboration with my clinical partner, Michael Bolognesi, MD. We often have multiple residents working on a variety of projects at once. My research interests lie mainly with clinical research in hip and knee replacement, including biomechanical studies, outcomes research, and clinical trials. I have also begun collaborating with basic science colleagues on biomarker research
