Previous research on gender equality in Higher Education indicates that women do not leave academia to a greater extent than men, but their academic career tend to be slower. This paper examines how the content and practice of academic work may differ between men and women in different disciplines. How do men and women spend time on teaching research, administration and scientific tasks? Are there differences concerning leadership assignments and scientific mission between gender and discipline? The study is based on data from a larger study of two faculties at a large Swedish university. The results show large differences between men and women concerning activity in scientific missions meanwhile differences concerning leadership assignments. In both faculties, women on teaching positions have a higher proportion of research in their employment than men, but the gender gap is small. The conclusion is that the vertical mobility can be analyzed in terms of scientific production. Future research should specially focus on the gender dimensions of the context in the academic scientific production.
