Lain M.

Lain (“they/them”) is non-binary and transfeminine. They completed a bachelor’s degree in applied mathematics and studied bioinformatics and computational biology at the Rochester Institute of Technology in New York. After withdrawing from their Ph.D. program, Lain migrated to the much warmer climes of the San Francisco Bay Area to work in tech.

As a person entrenched in nightlife community, specifically raving, Lain reformed and ran a nightlife harm reduction non-profit chapter for over 3 years, Bay Area DanceSafe ( At DanceSafe they produced harm reductive literature on pertinent drugs and organized harm reduction booths at various festivals and raves. Through this direct outreach to the nightlife community, Lain led volunteers providing peer education on drugs, consent, sex education, and other pertinent topics as well as substance adulterant testing and harm reduction interventions. As a chapter head, they advocated for the normalization of harm reduction and the reform of drug policy working with peer organizations such as the Drug Policy Alliance (DPA), the Students for Sensible Drug Policy (SSDP), the Multidisciplinary Association for Psychedelic Studies (MAPS), and also by speaking at several events in the Bay Area.

As Lain began to medically transition, they began to passionately research endocrinology and transgender medicine. They go by u/Klafka612 on Reddit and moderate several subreddits related to transgender hormone therapy including r/TransfemScience, r/AskMtFHRT, and r/TransBreastTimelines.
