Recruiting and retaining diverse individuals in science is integral to promoting scientific progress, and in order to do this, science must first become more inclusive for all individuals. Currently, science, technology, engineering and math (STEM) academic environments are often considered to be unwelcoming and unfriendly spaces for lesbian, gay, bisexual, transgender, queer, intersex and asexual (LGBTQIA+) individuals. Studies show that LGBTQIA+ professionals face systemic inequalities across STEM fields and LGBQ undergraduates are less likely to persist in STEM majors than non-LGBQ students. To create a more diverse and inclusive STEM community, STEM must work to eliminate these inequalities and feelings of exclusion by further understanding more about the experiences of LGBTQIA+ individuals in STEM learning environments, such as undergraduate biology classrooms.
