When I started grad school, a (female) staff member told me – if you go into Prof X’s office, don’t let him shut the door behind you. She elaborated. So, I knew that I and the other female grad students could not discuss science with Prof X in the same way that the male grad students could. That Prof X would not be thinking about science if we went to him for discussions. And Prof X was the THEE big shot in our dept. So, I understood right from the start – you are not equal. You will not have the same opportunities here.
