About

Researcher, advocate, community builder.

I’m Jonah Segil — a senior at Mira Costa High School working at the intersection of public-health research, LGBTQ+ advocacy, and youth-led civic organizing in the South Bay of Los Angeles.

I grew up in Manhattan Beach and have spent the last several years building work that connects three communities I care about: the researchers studying how policy shapes health outcomes, the policymakers writing those policies, and the young people most affected by them.

At UCLA’s Center for LGBTQ+ Advocacy, Research & Health (C-LARAH), I serve as a research intern — co-authoring presentations, contributing to a commentary in The Lancet, and helping lead a grassroots fundraising effort that raised nearly $150,000 for the Center after federal funding cuts threatened its work.

Locally, I founded the Southbay Social Advocacy Coalition, which produced the first-ever South Bay Queer Prom in 2026 — an all-ages, judgment-free event for LGBTQ+ students. I also organized and led a peaceful walkout of roughly 900 Mira Costa students protesting unlawful ICE detentions, and I sit on the Beach Cities Health District’s Youth Advisory Council.

The through-line is the same in every project: youth-led work that bridges data, policy, and community — and treats young people as collaborators, not an audience.

Approach

Three principles guide the work.

01

Evidence-based

Decisions should be grounded in research. Advocacy is strongest when it carries data, citations, and lived experience together.

02

Youth-centered

Young people are not a future constituency — they are a current one. Programs work better when students help design them.

03

Community-first

Health, policy, and civic life are local before they are national. Lasting change is built block by block, school by school.
