About Me [CV]

I am an assistant professor in Computer Science at NYU Shanghai.

Before that, I was a postdoc at New York University, UC Berkeley and Northeastern University.

I did my Ph.D. at the Chinese University of Hong Kong, under the supervision of Andrej Bogdanov.

My research interests are theoretical computer science, in particular cryptography, computational complexity and pseudorandomness.
