Cid organized an "Indigenous in Physics" meeting at the SACNAS annual conference in 2017. In 2020, along with Brittany Kamai, Franklin Dollar, Corey Gray, and other physicists, Cid helped launch the Society for Indigenous Physicists. The same year, Cid also helped lead the #ShutDownSTEM, #ShutDownAcademia, and #Strike4BlackLives protests to address anti-Black racism in academia and STEM fields.
