[News] (2023) [Award] Thrilled to learn that our CARMEN+ Tier 1 UTC proposal is awarded by USDOT! Excited to leverage this award to keep exploring and addressing cybersecurity challenges in autonomous driving and intelligent transportation systems.

[News] (2023) Excited to be invited by the IEEE Intelligent Transportation Systems Society to serve on the IEEE Emerging Transportation Technology Testing (ET3) Technical Committee! Will leverage this opportunity to contribute to the emerging transportation technology testing methods development and standardization from the security/privacy angles.

[News] (2023) [Award] Huge congratulations to my student Takami Sato for winning the Graduate Dean’s Dissertation Fellowship! This is one of UCI's most distinguished fellowships and only awarded to the top 1-2 students per school. Well deserved and very proud of you!

[News] (2023) [Award] Huge congratulations to my student Takami Sato for winning the Public Impact Fellowship! This is a highly prestigious fellowship at UCI that is only awarded to top 15 students across all schools. Due to the emphasis on public/societal impacts, it is especially rare for CS student to win it. Very proud of you!

[News] (2022) [Award] Thrilled to annouce that I just received the NSF CAREER award! Excited to leverage this award to keep exploring AI security in the emerging Internet of Autonomous Things (IoAT) such as autonomous cars, drones, and robots.

[News] (2022) Excited to be invited by NIST to serve on the AI panel & focused group on standards & performance metrics development for on-road autonomous vehicles! I am the only invitee on AI security from academia and will leverage this opportunity to contribute to the standard and metric design discussions from the security/privacy angles.

[News] (2021) [Award] Congratulations to Kanglan Tang, an undergraduate student in my group, for receiving the prestigous UCI Chancellor’s Award for Excellence in Undergraduate Research! This award is given to only 1 student per school. Kanglan is extremely excellent with a 1st-author paper published, presented herself, and accepted for demos at multiple academic venues, and also awarded multiple travel grants to top-tier security venues. Look forward to her continued success at UC Berkeley!


[News] (2021) [Award] Our undergrad cyberseucrity team Cyber@UCI finished 5st place nation-wide at National CCDC, out of 168+ university/college teams in US! Absolutely a huge achievement for the first time at National. Can't wait for next year :)

I am an Assistant Professor in the Department of Computer Science (CS) at the University of California, Irvine. I am also affiliated with the Department of Electrical Engineering and Computer Science (EECS), the Institute of Transportation Studies at UC Irvine (ITS-Irvine), the Center for Embedded and Cyber-physical Systems (CECS), the Institute for Software Research (ISR), and the UC Irvine Cybersecurity Policy & Research Institute (CPRI). Before coming to UCI, I received my Ph.D. degree from Computer Science and Engineering at the University of Michigan, Ann Arbor in 2018.

My research interest broadly lies in the security and privacy of computer technologies that are of high criticality to our daily life and society. So far, my focus has been mainly on the security/privacy issues in emerging AI/systems/network technologies, especially the latest ones with high societal impacts such as those powering the emerging AI-enabled autonomous vehicles and intelligent transportation systems.

The major theme of my research is to proactively address security challenges through systematic problem analysis and design, leveraging techniques such as optimization, static/dynamic program analysis, formal methods, defense principles, and data-driven methods. My research has developed such approaches to systematically discover, analyze, detect, and fix security vulnerabilities in a wide range of important computer systems and components such as the AI/software stack in emering autonomous cars/drones/robots, intelligent traffic light, smartphone systems, critical network protocols (e.g., TCP), DNS, GUI systems, access control systems, etc.
