About me
I am a Senior Software Engineer at Certik, a leading company in Web3 security.
With extensive experience in software security, program analysis, operating systems, and blockchain security, I am passionate about leveraging automated program analysis techniques to enhance the security and reliability of software systems. My focus includes securing the critical implementations that power everyday technology, with a particular emphasis on operating systems. Additionally, I have a strong interest in designing and building high-performance, secure systems and infrastructures.
I received a Ph.D. in Computer Science from UC Irvine, advised by Prof. Ardalan Amiri Sani. My research explores the intersection of operating systems and security. My work has been published in top-tier conferences, including ACM EuroSys, ACM MobiCom, and ACM ASPLOS. I have a B.Sc. degree from the Department of Computer Science of Huazhong University of Science and Technology (HUST). Before coming to UCI, I worked with Prof. Chen Tian on datacenter networks.
