About Me [CV]

I am an associate professor in Computer Science at NYU Shanghai.   I am on leave this year visiting Prof. Kai-Min Chung.  

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. 

I am recruiting postdocs with multiple opening positions. Please don't hesitate to contact me via email if you are interested.
