About Me

Hi! I am a PhD candidate in Computer Science at National University of Singapore, fortunately advised by Prof. Jiaheng Zhang. I had the previledge to work with Prof. Dawn Song, Prof. Neil Gong, Prof. Chao Zhang. I have also interned at Microsoft Research Asia.

My recent research focuses on applied cryptography, especially zero-knowledge proof and its intersection with AI auditing.

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