Hi, Welcome! I am an assistant professor of computer science at Singapore Management University. Before SMU, I was a Gladwin Development Chair Assistant Professor at Illinois Institute of Technology. I had the postdoctoral training at Cornell University and University of Utah, working with Prof. Elaine Shi & Prof. Mu Zhang, and obtained my PhD in Computer Science from UC Riverside in 2019, advised by Prof. Heng Yin. My research interests mainly lie in different aspects of Computer Security, including mobile security, system security, software testing, blockchain security and AI security. I enjoy solving emerging security problems by leveraging program analysis techniques and deep learning.
PhD position has been filled for Fall 2024. Please check back later.
One postdoc position (co-advise with Prof. Debin Gao) available!
