In this project, I examine the emotional and lived experiences of women of color (WOC) graduate students in science, technology, engineering, and mathematics (STEM) and how they embody and negotiate racism, classism, and sexism in academia, particularly in White, men-dominated STEM spaces. I utilize critical race theory and intersectionality to shed light on how WOC draw upon their intersecting identities, marginalization, and sense of community to navigate and resist oppressive environments. Specifically, I highlight the ways they experience racialized emotions and leverage vulnerability to resist dominant academic norms and controlling images to preserve their holistic selves, engage in critical reflexivity to challenge harmful mentoring practices, and activate ethics of the embodied self and care through their work, relationship building, and visions of themselves as scientists. This study extends our current understanding of the experiences of WOC in higher education by providing nuance to their experiences in STEM.
