The Blue Ridge Institute for Medical Research has posted a series of ranking tables based on NIH awards in Fiscal Year 2010. Unfortunately it is by total costs (direct plus indirect) so there will be some bias depending on the negotiated indirect cost rate.
I took a look at the PI lists in Basic Science and identified the number of women listed in the top 25:
Anatomy/Cell Bio: 8
Not so good. Okay, what's my best bet here from the clinical departments? hmm, how about:
Clinical OB/GYN: 8
Family Med: 9
I may have miscounted one name or so per list but no worse that that. And yeah, I know we talk about he dismal stats for women in science all the time, and how as the pyramid narrows it gets worse and worse. But it sure does have some umph to look at the numbers again, doesn't it?
