I am Ph.D. candidate under the supervision of Prof. Ke Yi. My research interests includes database theory and algorithms, data security and privacy. I was a group member of AAA between 2015 and 2017, which is a security team of ZJU. I was in charge of solving reverse engineering and cryptography related problems in CTF competitions.
