This program trains foreign biomedical scientists in epidemiologic, clinical, behavioral, and laboratory methodologies which can be applied to AIDS investigation. It provides foreign investigators with direct experience in AIDS research, both in the U.S. and in their home countries. This program also provides U.S. investigators from the University of Washington with field experience in AIDS research in an international setting and fosters international multidisciplinary collaborative research on AIDS through the formation of institutional affiliations between the University of Washington and foreign institutions. The goal of the program is to further international collaborative AIDS research through bilateral scientist exchange. The UW Program was begun in 1988 and has focused on multidisciplinary research on HIV-1 epidemiology and prevention, with Kenya as a primary target country. Many appointments have been provided for Kenyan scientists to receive research training in Seattle and for US investigators to receive field research experience in Kenya, where the HIV/STD Research Project has emerged as a center for excellence in HIV-1 research.
