Wen Cheng  

Bonjour! I am an incoming Ph.D. student at the University of Washington, working with Prof. Shyam Gollakota. Previously, I earned Master's degree with honors from Nanjing University, where I was advised by Prof. Wei Wang.

My research interests including wireless sensing and mobile computing. I also do some fun things about LLM.

I had an exciting research intern journey at Microsoft Research Asia (MSRA) and be honored to work with Prof. Jie Xiong. I also had a wonderful intern experience in ByteDance during my undergrad years.
