Hi, I'm a Research Fellow from National University of Singapore. My research interests include applied cryptography, especially on practical secure computation. I like combining secure computation techniques with data structure to design efficient protocols for privacy-preserving applications.

Previously, I was a Ph.D. student at Shandong University, where I was advised by Prof. Qiuliang Xu. Before that, I completed my bachelor degree at Harbin Engineering University.
