Brief Biography
  • Dr. Xiao is an assistant professor at the school of computer science and engineering in Southeast University, China. He received his PhD degree on 2011 from the computing department of Hong Kong Polytechnic University, under the supervision of Prof. Bin Xiao and Prof. Jiannong Cao (IEEE fellow). Afterwards, he joined the computer science department of Georgia State University as a postdoctoral researcher, where he worked with Prof. Wenzhan Song (now chair professor of UGA) from February 2012 to March 2013. Then, he went to computer science department at University of Florida as a postdoctoral researcher, where he worked with Prof. Shigang Chen (IEEE fellow) from April 2013 to May 2014. He joined Southeast University of China on May 2014.
  • M.Sc. Opportunity: In general, we are looking for good master candidates in the areas of network security, big network data, resource-constrained analysis of data streams, and wireless powered systems. Please send me your CV and publication list if you have interest to join our team.

  • "In my experience, most stuff that you start is mediocre for a really long time before it actually gets good. And you can't tell if it's going to be good until you're really late in the process. So the only thing you can do is have faith that if you do enough stuff, something will turn out great and really surprise you."
