About Me

I am a Professor in the School of Computer Science at Northwestern Polytechnical University (NWPU). I obtained my Ph.D. degree in Computer Science from City University of Hong Kong (CityU) in October 2018, under the supervision of Prof. Cong WANG (IEEE Fellow). Before that, I obtained my M.Sc. degree in Information Engineering from The Chinese University of Hong Kong (CUHK) in November 2013 and B.Eng. degree in Software Engineering from NWPU in July 2010.

[Closed] I am looking for self-motivated students (1 PhD and 3 Master) to start in fall 2025 at the School of Computer Science at NWPU.
[Opening] One postdoc position is available. Welcome to join us if you have research experience in the following areas: Industrial Internet, Secure Crowdsensing, Distributed Storage Networks, etc.

Research Interests

Trustworthy Crowd Computing, Privacy-Preserving Computing, Edge Intelligence, Decentralized Cloud Storage, etc.
