Bio

I am a professor at Princeton University and co-founder of Crosslayer Labs (YC W26). I specialize in the field of cybersecurity/privacy and am the recipient of the ACM Grace Hopper Award. My research has helped secure every single web connection (HTTPS) worldwide and enhanced the security of deployed LLMs (e.g., GPT 3.5 and GPT4V at OpenAI).
