Kexun Zhang

I am a second-year Ph.D. student in computer science at Carnegie Mellon University, working with Lei Li and William Wang(UC Santa Barbara). I got my bachelor's in CS from Zhejiang University. I'm interested in natural language processing.

Fun stuff

I was a competitive programmer in Olympiad in Informatics and International Collegiate Programming Contests. I'm a silver medalist at CNOI, a gold medalist at ICPC Asia Regional, and a Master at Codeforces.

I'm an amateur performer of Xiangsheng (aka crosstalk), which is a Chinese stand-up comedy performed by two people.

Other than Mandarin Chinese, I'm a native speaker of Taizhou Wu. I'd be really happy to chat with you in it.
