Scholar and pop culture historian Jennifer K. Stuller will present “Using Their Powers for Good: Geektivists, Geek Grrls, and Gaymers” at 10 a.m. Saturday, June 20 at Langley Library, 104 Second St.

Stuller is a Seattle writer, scholar and pop culture historian. Her talk, presented by Langley Library and Humanities Washington, is free and open to the public.

Stuller contends that geek activists, geek “grrls” and “gaymers” are making the personal political. Inspired by their love of fandom, tech, comics, games, television, costuming, and conventions, they are using their powers of good to challenge the self-appointed gatekeepers of geekdom with efforts that ensure their beloved culture is progressive, representative, and inclusive.

She will discuss how people and organizations are using community-building to create alternative spaces, crowd-sourcing to circumvent traditional modes of production, media criticism to challenge and raise awareness, and performance to subvert gender norms.

Stuller is co-founder of GeekGirlCon — an organization dedicated to the recognition, encouragement and support of women in geek and pop culture and STEM (science, technology, engineering and mathematics). She is an author and contributor to multiple publications, including Ink-Stained Amazons and Cinematic Warriors: Superwomen in Modern Mythology, and the editor of Fan Phenomena: Buffy the Vampire Slayer. She regularly appears at the Comic Arts Conference, the Slayage Conference on the Whedonverses, and San Diego Comic-Con International.
