Dr. Lunn is a physician-scientist investigating sexual and gender minority (SGM) health and utilizing existing and emerging technologies to characterize the health and well-being of these underrepresented and vulnerable populations.

Dr. Lunn’s work focuses on improving understanding of the factors that positively and negatively influence SGM health including research on SGM health disparities, SGM societal experiences, provider education about SGM health, and institutional climate towards SGM people.

Dr. Lunn is the co-director of The PRIDE Study (, a national, online, prospective, longitudinal general health cohort study (launched May 2017) of over 28,000 SGM adults. The PRIDE Study’s state-of-the-art web-based research platform enables robust participant recruitment, cohort management, real-time cohort statistics, comprehensive survey administration, facile deployment of studies to cohort segments, and linkage with other health data sources. Dr. Lunn is also the co-director of PRIDEnet, a participant-powered research network of SGM people that engages SGM communities at all stages of the biomedical research process: research question generation and prioritization, study design, recruitment, participation, data analysis, and results dissemination. PRIDEnet accomplishes its goals through a highly active Participant Advisory Committee and a Community Partner Consortium comprised of ~32 SGM-serving health centers, community centers, and service/advocacy organizations across the country. Dr. Lunn mentors research trainees at all levels from undergraduate students to junior faculty members.
