Matthew Spinelli, MD, MAS
Associate Professor
Medicine
School of Medicine

More recently, I lead projects on development of adherence measurement techniques for doxycycline post-exposure prophylaxis, including a directly observed therapy randomized trial. In terms of educational initiatives, I am the co-director of the Implementation Science Short Course and the Individual-Level Intervention Design course in the UCSF Department of Epidemiology. As an HIV/ID clinician, I serve as the PrEP Medical Lead for the Ward 86 Clinic. Finally, I am a member of the Partnership for Research in Implementation Science for Equity, a collaboration between the SF Department of Public Health and UCSF that seeks to use implementation science methods to advance health equity.
