Each SHARP scholar is matched with a mentor team, with whom they work throughout the summer. These mentors provide guidance on the scholar’s project, serve as a sounding board for the scholar’s educational career and goals, and provide coaching on how to work in a public health research environment.

  • Holly Nishimura, PhD, MPH

    Holly Nishimura, PhD, MPH, received her PhD from the Department of International Health from the Johns Hopkins Bloomberg School of Public Health. Dr. Nishimura’s research interests include understanding the social and structural factors that contribute to inequalities in health outcomes globally, with a particular focus on gender and economic inequalities. She is also actively engaged in efforts to decolonize global health and improve equity and inclusion in academia. Her dissertation research used a mixed methods approach to understand the relationship between transactional sex and HIV among men in Rakai, Uganda.

    Dr. Nishimura received the Fulbright-Fogarty and Ruth L. Kirschstein National Research Service Award (NRSA) from NIMH for her predoctoral training. Prior to entering the Ph.D. program, she received an M.P.H. in Maternal, Child, and Adolescent Health and B.A. in Integrative Biology from UC Berkeley. As a TAPS fellow, she is primarily working with Dr. Carol Camlin on the Owete study, which uses a social network approach to promote HIV self-testing and linkage to care among fishermen in Kenya. She is also working with Drs. Sheri Lippman, Marguerita Lightfoot on the Black Economic Equity Movement project, a guaranteed income intervention for black young adults in Oakland and San Francisco.

    Matthew Spinelli, MD, MAS is a HIV/ID physician with training in implementation science methods who uses these approaches to support pre-exposure prophylaxis (PrEP) implementation, PrEP/HIV ART adherence, and PrEP persistence/HIV retention in care. A key tool they are using in this work is a point-of-care urine tenofovir test that can provide real-time adherence information to clinicians to drive adherence interventions. More recently, he lead projects on the intersection of the HIV and COVID-19 epidemics using epidemiological, translational, and sociobehavioral methods. In terms of educational initiatives, he is the co-director of the Implementation Science Short Course and the Individual-Level Intervention Design course in the UCSF Department of Epidemiology.
