Kuan Cheng   程 宽

I am an Assistant Professor at Peking University, Center on Frontiers of Computing Studies (CFCS).

My research mainly focus on Computational Models and Complexity, especially Randomness in Computation and Coding Theory. I'm also interested in Machine Learning, Quantum Computing and other topics in Computer Science.

Previous Work & Education Experience

Before I came to Peking University, I was a postdoc at The University of Texas at Austin, hosted by David Zuckerman.

I achieved a PhD degree from Johns Hopkins University, Computer Science Department, advised by Xin Li.

Before that I obtained a master degree from Tsinghua University and a bachelor degree from Shandong University.
