Siyao Guo

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

Before that, I was a postdoc at New York UniversityUC 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. 

Here is my CV (Last updated: 2019-Jan-04).   You can reach me at
