Programmer. Bachelors, Masters, and PhD in theoretical physics. Musician. Hardcore gamer. Staunch Linux user. Convicted computer hacker. I used to be a theoretical physicist. Now I'm a programmer/quant on Wall street.
If I had to live life over, I would've become a game programmer. My dream job would be to work at id Software or some other big name game company. I would love nothing more than game programming all day long. :)
