I am a 6-th year CS Ph.D. candidate at UC Irvine working with Prof. Qi Alfred Chen.

My research interest is CPS/IoT autonomy software security with a focus on autonomous driving and intelligent transportation systems security. Recently, I have been mainly working on the security of industry-grade autonomous driving systems, including those providing different levels of driving autonomy (e.g., Level-2 and Level-4). Previously, I have also explored other security areas such as compiler-assisted countermeasures for fault and side-channel attacks and efficient isolation for Linux kernel subsystems.

Before joining UCI, I graduated with a M.S. and B.E. from North Carolina State University, Raleigh and Hangzhou Dianzi University, China, respectively.


May 11, 2022 I successfully defended my Ph.D. dissertation titled “Security Challenges and Defense Opportunities of Connected and Autonomous Vehicle Systems in the Physical World”!
Jan 6, 2022 A paper is accepted to the The Network and Distributed System Security (NDSS) Symposium 2022.
Oct 8, 2021 I received The Beall Family Foundation Graduate Student Entrepreneur Award in Computer Science. Thanks, Beall Family Foundation!
Aug 10, 2021 This year’s AutoDriving CTF is now ended. More than 100 teams attempted and 93 teams had valid scores! Among them, 4 teams finished all 20 challenges, and 59 teams solved at least one non-trivial challenge. Checkout the news from some of the winning teams: [六出祁山@BJTU], [Cacti@UB], [Redbud@THU]. Congrats!
Jul 19, 2021 I am organizing the AutoDriving CTF on behalf of the UCI ASGuard group together with Baidu Security X-Lab. This year it will be a hybrid (online and onsite) contest as part of DEF CON 29!! The offical contest time will be 24 hours starting from 6 pm Aug 5 PT. Before that, welcome to check out some demo challenges. Enjoy autonomous vehicle hacking!
