Edward Yelin, PhD, has been on the faculty of the Division of Rheumatology and Philip R Lee Institute for Health Policy Studies at UCSF since 1980. Dr. Yelin is perhaps best known for his work on employment among persons with arthritis and other chronic diseases. A second major thread to his research concerns studies of the impact of changes in the health care system on persons with arthritis. Finally he has been involved in studies documenting the economic and social impacts of chronic disease and disability. As part of this research, he authored the chapter in several volumes of The Burden of Musculoskeletal Disease in the United States (BMUS) on the economic impact of these conditions. He now serves as Co-Chair of the on-going BMUS project.
