About me

I am a second-year PhD student in the theory group in Princeton University, where I am fortunate to be coadvised by Prof. Ran Raz and Prof. Alex Lombardi. I have found and am exploring my interests broadly in TCS, including complexity theory, cryptography, and their interplay.

Prior to joining Princeton, I graduated from Yao Class at Tsinghua University. During my undergraduate, I was fortunate to be advised by great people. I was fortunate to work with Prof. Yilei Chen at Tsinghua who sparked my interest in cryptography. During 2022 I had an amazing time at Reichman University and NTT Research working with Prof. Elette Boyle and Prof. Yuval Ishai.
