Thomas J. Coates Ph.D.

Professor of Medicine

Thomas J. Coates PhD is the Michael and Sue Steinberg Endowed Professor of Global AIDS Research within the Division of Infectious Diseases at UCLA.  He also leads the Program in Global Health at UCLA.  He co-founded the Center for AIDS Prevention Studies (CAPS) at UCSF in 1986 and directed it from 1991 to 2003.  He was the founding Executive Director of the UCSF AIDS Research Institute, leading it from 1996 to 2003.  His areas of emphasis and expertise are HIV prevention, the relationship of prevention and treatment for HIV, and HIV policies.  His domestic work has focused on a variety of populations, and he is currently finishing a nationwide clinical trial of an experimental HIV preventive intervention focused on high-risk men.  He is also finishing domestic trials of post-exposure prophylaxis.  With funding from USAID and WHO, he led a randomized controlled trial to determine the efficacy and cost-effectiveness of HIV voluntary counseling and testing for individuals and couples in Kenya, Tanzania, and Trinidad.  He is now directing a 46 community-randomized clinical trial in South Africa, Zimbabwe, Tanzania and Thailand to determine the impact of strategies for destigmatizing HIV on HIV incidence community-wide.  He is also leading a prevention clinical trial in South America as part of a 5-country effort, and has a trial in China to determine the impact of prevention in the context of care.  He is co-principal investigator of the NIAID funded HIV Prevention Trials Network, and is conducting policy research domestically and internationally.  He was cited in Science in 2002 as the 4th highest funded scientist in the clinical, social, and behavioral sciences and was elected to the Institute of Medicine in 2000.
