Hi Justin,
My husband and I met in graduate school (grades 17-22!!) because we were both training to be scientists. Now we are both scientists and working at the same laboratory at the University of California in Berkeley. I know of many other people who are scientists and married to scientists. Personally, I think this is great because my husband and I understand each other's work, we both know the people we work with, we can take one car to work, and we can travel to conferences together without one person being left out.
