Wei Gong

Professor, School of Computer Science and Technology, University of Science and Technology of China

My research focuses on wireless networks, distributed computing, and Internet-of-Things. Previously, I had worked at SFU, UOttawa, and Tsinghua Univ. After receiving my B.E. in computer science at HUST, I went to Tsinghua Univ., where I was awarded my M.E. in software engineering and Ph.D. in computer science.

I am looking for highly motivated students, postdocs, and researchers in or around networking areas. If you are interested in working with me, please feel free to drop me an email at weigong@ustc.edu.cn.
