Hi, I'm a Research Fellow at Nanyang Technological University, Singapore. My research interests focus on applied cryptography, especially in the area of practical secure computation. I like combining secure computation techniques with data structures to design efficient protocols for privacy-preserving applications. My recent work focused on developing secure computation protocols with enhanced security.

Previously, I was a Research Fellow at the National University of Singapore. I completed my Ph.D. at Shandong University, where I was advised by Prof. Qiuliang Xu. Before that, I obtained my Bachelor degree in Computer Science at Harbin Engineering University.
