Good question, I think I’d like to be doing space research.. some sort of Astrophysics. I studied this for me degree and for my masters degree but the only problem for me was that you can’t really do many experiments. It’s still amazingly interesting though.
Well I’ve moved a couple of times (from Quantum Physics to Medical Physics to Social Physics) so I’d like to stay where I am for a while! But I guess the philosophy of science would an interesting area.
