My research centers on reducing health disparities experienced by sexual and gender minority (SGM) adolescents. Broadly, my research focuses on understanding how close relationships and social networks shape the health and well-being of sexual minority adolescents. My long-term goal is to leverage close relationships to reduce SGM adolescent risk behaviors, particularly substance use and HIV transmission behaviors, by strengthening key support systems including relationships with parents, peers, and romantic partners.
A second area of my research focuses on identifying minority stressors as risk factors for poor mental health outcomes, substance use, and sexual risk taking among SGM adolescents. I am particularly interested in understanding the associations between systemic minority stressors, including anti-LGBTQ+ state and national policy, on SGM adolescents health.
I collaborate closely with other IUSM colleagues through the Adolescent Behavioral Health Research Program and Children’s Health Services Research. Additionally, I collaborate with investigators at Hunter College, University of Southern California, and other institutions.
I provide evidence-based psychotherapy to children and adolescents presenting in the Division of Adolescent Medicine within the Department of Pediatrics. My clinical interests falls into two broad categories: (1) providing evidence-based and affirming psychotherapy to sexual and gender minority adolescents who are presenting with mental health concerns that are exacerbated by experiences of systemic, interpersonal, and internalized minority stressors; (2) and providing evidence-based psychotherapy to support children and adolescents presenting with cognitive, emotional, and behavioral challenges associated with acute and chronic illness.
