About

I am an applied community health scientist specializing in sociobehavioral research and public health intervention development. I apply health behavior and implementation science frameworks to design, test, and evaluate interventions that address the multilevel factors shaping health disparities among marginalized and minoritized populations. My work has centered on HIV prevention science and sexual and gender minority health, with growing interests in workforce health, substance use disorders, and digital health. I am committed to generating evidence that is rigorous, community-grounded, and actionable. Ultimately, I aim to advance the field of community health sciences while strengthening the public health infrastructure that serves communities most affected by health inequities and the frontline workforce that delivers their care.

Emerging Research Agenda

Work that centers community
and health equity.

Burnout Prevention Among the Public Health & HIV Care Workforce

The HIV response is only as strong as the people delivering it.

Burnout among public health and HIV frontline workers remains critically understudied. This developing research agenda aims to use qualitative methods and intervention mapping to generate evidence on how the public health and HIV workforce experience burnout and identify worker-driven strategies that are sustainable and feasible to support the public health and HIV care delivery workforces.

Substance Use, Addiction, and Health Disparities

Substance use and addiction are driving contributors to poor health and HIV disparities.

Substance use disorders disproportionately affect communities already bearing the greatest burden of HIV and health inequities. This developing research interest aims to improve substance use disorder prevention and treatment outcomes among marginalized populations, including sexual and gender minoritized communities and those with co-occurring conditions. I am particularly interested in how health systems such as the VA can deliver evidence-based, integrated behavioral interventions that address the intersecting epidemics of HIV and substance use, and in identifying the organizational barriers that prevent these communities from accessing the care they need.

AI & Digital Health Tools

Technology should serve the communities it was built to help.

AI & Digital Health Tools exist in a continuously evolving landscape. This developing research agenda aims to evaluate AI-enabled tools, including large language models and new digital health technologies, and understand how they can be harnessed for health promotion and disease prevention. Particularly, their capacity to strengthen public health infrastructure, with a focus on equity, ethics, and underrepresented communities.

"Cashing in on HIV Prevention: An Exploratory Mixed Methods Study Assessing the Preferences and Acceptability of a Pre-Exposure Prophylaxis-Based Conditional Cash Transfer among Black and Latino Men Who Have Sex with Men in Los Angeles County"

UCLA Fielding School of Public Health · Committee Chair: Dr. Michael Prelip · Defense: April 2026

An exploratory mixed methods study finding that cash transfer programs are an acceptable HIV prevention strategy for Black and Latino men who have sex with men in Los Angeles County. These findings contribute to the evidence base for using cash transfers to reduce HIV transmission among communities at greatest risk.
