Hi, I'm a Research Fellow at Nanyang Technological University, Singapore. My research interest focuses on applied cryptography, especially on practical secure computation. I like combining secure computation techniques with data structure to design efficient protocols for privacy-preserving applications. My recent work focused on designing secure computation protocols with malicious security.

Previously, I was a Research Fellow at 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.
