From PhD level physics professor:
I was at a conference on increasing the number of women and minorities in physics and engineering. A number of high level people had to give talks about what their school was doing along these lines. One guy showed a graph of the percent women in various engineering programs (with some having less than 5%) and suggested the way to get women into other engineering was to put bio in front of the name…as in bioaero engineering, because really it is just the name of the major that is the problem.
