About Me

Hi! I am a PostDoc at UC Berkeley with Prof. Dawn Song. I received my PhD from the National University of Singapore.

My research is at the intersection of LLM, security, and privacy, with a focus on building secure, verifiable, and auditable AI systems.

I am always open to collaborations. If you share similar interests, feel free to email me.
