Another thing to add is that, generally speaking, people love to talk about themselves. So you can shoot for anything in that "About Yourself" category that spans from professional to personal. I typically try to find something that will get things started (even if I completely don't care about the topic) and build rapport, and then try to steer the conversation towards fulfilling my agenda.
So for example, I might strike up a conversation with you about recent political events in Europe or logging and mining techniques which are destroying the environment (neither of which I care about), but as we go along, I'm going to try to steer our discourse toward what I want to know -- in this case, it might be on funding, ideas for research that I can "borrow," employment opportunities, eligible relatives or offsprings that might be looking for dates, etc.
