Currently lives: In R02/Hawking, mostly due to the science museum. He's used to barrack living and has few complaints about where he's chosen to stay.

How many credits: More than enough to support himself. He does both legit and not-so-legit doctor work (which, yes, would include organ running).

Other zones: Where ever his teammates are when they need him. He's also taken to exploring other zones for research purposes.
