Infectious disease modeling and policy analysis with an emphasis on strengthening national HIV responses, reducing HIV impacts and maximizing the returns on HIV investments; risk behaviors and epidemiology of HIV in Asia and the Pacific; public policy for HIV/AIDS prevention, care and treatment; International collaboration on health issues; responses to COVID-19 in Hawaii.
Dr. Tim Brown is a Senior Fellow in the Research Program at East-West Center where he directs a small team of epidemiologists and programmers in developing and applying tools for HIV modeling and analysis. He works closely with UNAIDS, the Global Fund, Avenir Health and national partners throughout Asia to improve national responses to HIV epidemics and ensure available resources are invested to produce the greatest benefits. He is a member of the UNAIDS Reference Group on Estimates, Modeling and Projection, an advisor to UNAIDS and the Global Fund on HIV modeling and evaluation issues, and an advisor to the Scientific Committee on AIDS and STD in Hong Kong. Before joining the Center, he was formerly assistant professor in electrical engineering, University of Hawai'i; adjunct assistant professor in the Program on Computing, Department of Mathematics, University of California at Los Angeles; and applications group manager, AMETEK Computer Research Division, Pasadena.
Consultancies: Joint United Nations Programme on AIDS, World Health Organization, Save the Children (UK), United Nations Development Programme, and Hong Kong Department of Health.
Professional honors: Research grants from UNAIDS, the Global Fund to Fight AIDS, Tuberculosis and Malaria, and Avenir Health.
