Dr. Bernthal is the Interim Chair and Executive Medical Director of UCLA Department of Orthopaedic Surgery and Chief of the Division of Musculoskeletal Oncology. He is a surgeon-scientist who leads one of the busiest sarcoma practices in the country while leading an NIH-funded basic science laboratory.
Dr. Bernthal’s laboratory developed and published a mouse model of post-arthroplasty infection that has become widely used by academics, regulatory officials, and industry. The model leverages a panel of bioluminescent bacteria to allow longitudinal real-time in vivo tracking of infection, while using immunomodulated mice so that fluorescence imaging can track immune response. This model has produced twenty peer-reviewed papers, numerous grants, and multiple awards, but perhaps most importantly, has been adopted by scientists from industry, academia, and the Food and Drug Administration. Dr. Bernthal was selected to lead the Orthopaedic Research Society’s 2017 symposium on “The Infected Implant” and represent the American Orthopaedic Association as an American-British-Canadian Traveling Fellow in 2017. He serves on the Executive Board of the Musculoskeletal Tumor Society and on the Board of Trustees for the Orthopaedic Research and Education Foundation.
Dr. Bernthal was born and raised in Washington D.C. He played Varsity Basketball at Princeton University while studying political science. He earned his medical degree from Cornell Medical School and did his residency at UCLA. He completed two fellowships -one in Orthopedic Research at UCLA and the other at the Huntsman Cancer Institute - and has been on faculty at UCLA since 2013.

Manish Agarwal
India
As the first dedicated full time Orthopaedic Oncologist in India, he setup the bone & soft tissue service at the Tata Memorial Hospital, Mumbai, the biggest Cancer speciality hospital in India. During the decade that he served there, he pioneered limb salvage surgery in India and also trained several doctors who are now practicing senior orthopaedic oncologists in different parts of the country. In the absence of a formal organ transplantation programme, he pioneered the use of radiated long bone allografts obtained from amputated limbs. He also developed the use of extracorporeal irradiation and reimplantation of bones. He also pioneered the development and use of an indigenously manufactured tumor prosthesis to make the limb salvage affordable. A completely novel hinged tumor knee prosthesis developed by him and the engineers is now under clinical trial at leading sarcoma centres in India. After serving at Tata Memorial for a decade he set up a orthopaedic oncology service at the P D Hinduja Hospital, a reputed private hospital in Mumbai. He now works from the Nanavati Max superspeciality hospital and continues to persue his interest in bioengineering. He has also setup a Sarcoma support group in Mumbai. He has published his work in many reputed journals and has presented at various international and national meetings and is a founding member of the Indian musculoskeletal oncology society. As a member of the education committee of the ISOLS, he has helped continue the teaching program of ISOLS during the pandemic.
