My name is Yajin Zhou (周亚金). I am a ZJU100 Young Professor (since 2018), with both the College of Computer Science and Technology and the Institute of Cyber Security Research at Zhejiang University, China. I earned my Ph.D. (2015) in Computer Science from North Carolina State University. You can find my PGP key here.

My research focuses on system security, i.e., identifying real-world threats and building practical solutions, currently in the context of embedded systems (or IoT devices). My research has been supported by National Natural Science Foundation of China (NSFC), and Alibaba Group.

I am serving the program committee for the following conferences. Please consider submitting your paper and/or attending the conference.

ACM CODASPY 2019 | ACM ASIACCS 2019 | IEEE EuroS&P 2019 | IEEE ICDCS 2019

I'm looking for motivated Ph.D./master students, postdocs and (visiting) research students who have a solid background in systems and/or security. If you enjoy building systems, we should talk.
