at Asiacrypt 2025

I am a Second-year PhD student at Brown University, doing Cryptography in the group of Professor Peihan Miao. I built Private Set Intersection systems (such as PICS and SA-PSI) that solves new-generation PSI problems that are much closer to practice and industry needs. More broadly, my interests lie in enabling secure and decentralized data analytics in the real world, using Cryptography. I did my Undergraduate study at Nanyang Technological University, where I was fortunate to be guided by Professor Wang Huaxiong and Professor Kiah Han Mao. I worked a lot in Coding Theory, especially the Sequence Reconstruction Problem for Deletion, during my Undergrad, and I'm still open to collaborations.

News:

• Jan 2026: PICS got accepted to Usenix Security 2026!
• Dec 2025: I won Funniest Talk at Asiacrypt 2025 Rump Session!
• Aug 2025: Our Structure-Aware PSI paper got accepted to Asiacrypt 2025!
