I was fascinated by a recent study published in the Proceedings of the National Academy of Sciences (link), showing that A) male faculty tend to have fewer female graduate students and postdocs than female faculty (not news to most of you in the sciences), and B) "elite male faculty" - that is, those with major career awards, members of the National Academy of Sciences, etc. - trained significantly fewer women compared to other male scientists.

There are many possible explanations for the lack of women in the sciences (some of which I have explored on these pages), but there is no doubt that this is a problem that needs to be addressed. This study suggests yet another mechanism through which the pipeline to faculty positions gets narrowed for female students.
