This project aims to investigate how gender affects career paths and progression in surgery, and the implications of this for surgical practice and innovation. This is important because women surgeons show gendered patterns of sub specialty selection, experience a pay gap relative to men, and are less likely to be involved in innovation. Theories of epistemic injustice offer new ways of understanding workplace gender discrimination, and the project will use qualitative methods to test their applicability in surgery. The project will contribute new knowledge about invisible barriers to women’s career progression in surgery and their involvement in innovation, and make theoretical contributions to feminist epistemology.
