John Sauceda
Co-Director
John is an Associate Professor In Residence and a health psychologist in the Division of Prevention Science in the Department of Medicine. He co-directs mentoring programs for post-doctoral fellows and early-career faculty, graduate students, and undergraduate students: (1) The UCSF Center for AIDS Research (CFAR) Mentoring Program, (2) the CFAR Scholars Research Program, (3) the Summer HIV/AIDS Research Program, and (4) CALIBER’s Pilot Research and Training Program, as well as being Co-Director of the Developmental Core at the Center for AIDS Prevention Studies (CAPS). He has two research programs that blend principles and methods from health, clinical and quantitative psychology. The primary line of research aims to understand and intervene on factors to address HIV-related disparities in the U.S., Mexico and Uganda, and he uses the Multiphase Optimization Strategy (MOST) to design more dynamic and efficient interventions. His second line of research aims to conduct social and behavioral science research to help address some unresolved challenges in HIV cure research, such as promoting consent understanding and measuring psychological experiences of participants going through risky HIV cure trials.
