I'm an Applied Research Scientist at Krafton AI, focused on the social impact of AI. My research spans social simulation, coding agents, and system optimization; before that, I was a white-hat hacker — a CTF player with a few KVEs to my name. The thread through it all: how frontier technology reshapes the people who live with it. I believe the best technology makes humanity happier, and I want to help build it.
