Several initiatives recognize the importance of transforming institutions, not just changing individuals, to diversify STEM (science, technology, engineering, mathematics) fields. Universities and colleges are distinctive gendered work organizations because workers (faculty) are highly educated and have authority in hiring, evaluation, and policy (shared governance). This article explores whether feminist sociologists are particularly well suited to guide institutional change to diversify the academy. Drawing on data from in-depth interviews with 24 feminist academic sociologists at the rank of associate or full professor, I analyze how their feminist and sociological identities intersect with institutional locations to create opportunities to transform the academy. Outsiders within, feminist sociologists revise and use the master’s tools to produce knowledge that improves recognition of, and ability to reduce, structural inequalities. Proficiency with these tools confers insider legitimacy and access to a “seat at the table” where disciplinary expertise and political commitments contribute to institutional change. Inevitably, these professors confront resistance, and in response develop strategies to advance their goals. Insights from feminist sociologists suggest that to transform universities to reflect the diversity of institutions and lived reality of contemporary faculty, it may be more useful to identify a set of commitments and principles that inform policies and practices, rather than specifying actions to support culture change.
