Chien-Liang Fok

I am a graduate research assistant in the Department of Computer Science at Washington University in Saint Louis. I am part of the wireless sensor network research group and Mobile Computing Laboratory. My advisors are Gruia-Catalin Roman and Chenyang Lu.

My primary research focus is on developing highly flexible middleware for wireless sensor networks. See Projects for more details.
