Abstract

Significance Despite decades of progress, men still greatly outnumber women among biology faculty in the United States. Here, we show that high-achieving faculty members who are male train 10–40% fewer women in their laboratories relative to the number of women trained by other investigators. These skewed employment patterns may result from self-selection among female scientists or they may result from conscious or unconscious bias on the part of some faculty members. The dearth of women who are trained in these laboratories likely limits the number of female candidates who are most competitive for faculty job searches.
