CAST-M is a new pathway to encourage doctoral student diversity in the fields of science studies, medical humanities, history of science and technology, and history of medicine. We aim to recruit and support emerging scholars from backgrounds that are traditionally marginalized in STEM-adjacent humanities fields. As a special track in the MA program in History of Science, Medicine, and Technology, we strongly welcome applicants critically engaging with science, medicine, technology, and engineering, their intersections with questions of race, gender, sexuality and colonialism, as well as in the Global South and in communities subject to systemic discrimination. A focus on the relevance of these histories to STEM-adjacent humanities fields offers urgently-relevant insights into the production and reproduction of race, gender, sexuality, and colonialism in everyday life.
