Professor of Medicine in UC San Diego's Division of Infectious Diseases and Global Public Health, Jill S. Blumenthal, MD, MAS, trained at Weill Cornell for medical school and internal medicine residency before completing infectious disease fellowship at UC San Diego in 2014. As Director of PrEP Services at UCSD's Owen Clinic, the panel at 4168 Front St runs same-day PrEP starts, quarterly lab monitoring, and gender-affirming hormone therapy on a referral schedule coordinated with community partners including The San Diego LGBT Community Center. Clinical rolls cover cisgender men who have sex with men, cisgender women, and transgender and nonbinary adults at risk for HIV acquisition, plus adolescents and adults living with HIV. Co-founder of UCSD's Transgender and Nonbinary Community Advisory Board in 2018 and lead developer of the UCSD Gender Health Program, the physician also co-chairs the UCSD Chancellor's Advisory Committee on Gender Identity and Sexual Orientation Issues. Active research threads on lenacapavir, rapid ART initiation, and tenofovir pharmacokinetics in trans adults on concurrent hormone therapy tie the Owen Clinic into wraparound HIV programs such as AHF Wellness Center - San Diego. The most complex work handled on this panel is HIV prevention and treatment for transgender adults on gender-affirming hormone therapy, where tenofovir concentrations and estradiol or testosterone levels have to be co-monitored against adherence and intimate partner violence risk factors.
