A comment by "Science Prof" shows how so very much further we have to go.
The fact that women have a “biological clock” means nothing. The issue is still one of people making choices and accepting the consequences.
In my graduate program, I would much prefer to have grad students who have no children. They are willing to work harder and will not be whining about having to be home by 5 p.m. Graduate school is extremely demanding — my graduate program often requires an 80+ hour/week commitment. Grad students who have children are often unwilling to make that sort of a time commitment and they often fall behind or flunk out.
This is simply the nature of graduate school. Attempting to make it more “family friendly” will 1.) Reduce the academic standards of the program to accomodate students who cannot make the required time commitment and, 2.) Raise the costs on everyone else — especially students without children, who will likely end up paying more in tuition to subsidize those who do have children.
In 30 seconds, I thought of 11 faculty members at my university who could have written this.
