Psifertex's professional security career includes stints as a senior security engineer for a major public university, a security researcher, and he even managed to slip in a few years writing for technical magazines. Through those roles, he has taught reverse engineering, vulnerability research, and web security at multiple universities, government organizations, and conferences. After dark, he likes participating in CTF games, winning the '07 RSA "Interactive Testing Challenge", and is very grateful to be a member of the '07-'08 Defcon CTF winning team, 1@stplace.
