AI Safety Research

I work on finding and fixing ways AI systems can fail. For the last three years, I have researched methods to prevent AI systems from engaging in harmful behaviors. Yet, my most recent work demonstrated how frontier models can engage in blackmail and deception when pursuing goals. Now, I am focused squarely on identifying and patching these vulnerabilities in autonomous AI systems.

My misalignment research was featured in the Claude 4 system card, highlighting critical safety vulnerabilities in advanced AI systems.
