I am Wei Zhang, assistant professor at cse department of university of connecticut. Before that, work at Microsft for more than 3 years after graduating from GWU.

From Sep 2008 to Dec 2014, I was a Phd student in computer science at Beihang University advised by Prof. Mingfa Zhu. Meanwhile, I was also a visitng student at Institute of Computing Technology Chinese Academy of Sciences (from June 2010 to July 2012) and at the George Washington University (from Nov 2012 to Oct 2014). I had my second phd life from Jan 2015 to Aug 2018 advised by Prof. Timothy Wood.

I am looking for highly-motivated Ph.D. students who have strong interests in cloud computing, distributed system, operating system, resource disaggregation, network system (NFV, SDN), edge computing, micro services, serverless computing, storage system and machine learning system. You are welcome to drop me an email with your materials such as CV and transcripts and mention my name in your application.

Research Interests:

  • Cloud computing and virtualiztion technologies
  • Distributed system
  • Network and storage system
  • Resource disaggregation
  • ML system
  • Edge computing
  • serverless computing
  • Resourde management
