About me
I obtained my PhD at the Department of Computer Science and Engineering, Hong Kong University of Science and Technology, where I had the privilege of being advised by Prof. Shuai Wang. I am working as a Postdoc at HKUST. I was once a visiting student at ETH Zürich, advised by Prof. Zhendong Su.
My research focuses on system dependability of privacy-enhancing technologies.
