GReG values
GReG is an apolitical academic consortium. Our code of practice seeks to promote a safe, inclusive, and scientifically productive environment, regardless of gender, geographic provenance, ethnicity, sexual orientation, religion, disability, and physical appearance. Since a community where people feel uncomfortable or threatened is neither healthy nor productive, GReG prohibits intimidating, threatening, or harassing conduct. These values are founded in the Codes of Conduct of the International Society on Subterranean Biology (ISSB) and primary funder, Curtin University.
