I'm not sure about math[1] but chemical engineering can (though not always) have a lot of overlap with bio-eng and med-eng, which parallels his argument somewhat. I'd be curious to see the degree to which a more detailed breakdown of gender differences both in engineering disciplines and scientific disciplines matches his thesis for sure. If his argument holds maybe physics would be more male, biology more female, and chemistry somewhere in the middle-ish?
[1]: Anecdotally, foreign students have made up a larger percentage of the female mathematics (and physics) graduate students I've known than of the male math (and physics) graduate students I've known, though I have no idea if my experience normal, sample size is very small and biased, etc.
