Orhun K. Muratoglu, PhD, is the Director of the Harris Orthopaedics Laboratory and Director of the Technology Implementation Research Center (TIRC) at Massachusetts General Hospital, Alan Gerry Scholar at Mass General, and Professor of Orthopedic Surgery at Harvard Medical School. He received his B.S. from Rennselaer Polytechnic Institute in Materials Science and completed his doctoral work at the Massachusetts Institute of Technology in the Program for Polymer Science and Technology. Dr. Muratoglu played a key role in the discovery of highly cross-linked UHMWPE, a more wear-resistant polymeric material for load-bearing applications in total joints. He also pioneered the use of the antioxidant vitamin E to further stabilize the highly cross-linked UHMWPE. Medical implants fabricated using technologies developed by Dr. Muratoglu have been in clinical use since 1998, with over 7 million implantations worldwide. Dr. Muratoglu continues his research on UHMWPE and infection and pain management technologies in total joints. He also directs research in the design of more functional joint implants at the TIRC.
