Hi there, I'm Rex. I co-founded General Analysis, a cybersecurity lab dedicated to measuring and improving how frontier models perform on critical cyberdefense tasks.

I grew up in Taiwan, the most cyberattacked island in the world, and developed a taste for explo(r|it)ing the boundaries of technology. To date, I have disclosed 200+ CVEs and earned $200k+ in bug bounties.

Previously: reasoned @ DeepMind; researched AI-driven drug discovery in Matt Thomson's lab.
