I’m currently working as a researcher in Huawei. I received the Ph.D. degree in Computer Engineering from Northwestern University, United States in 2021, advised by Prof. Qi Zhu, and bachelor degree in Microelectronics from University of Electronic Science and Technology of China in 2016.
My research interests include sensor-fusion based indoor localization, autonmous driving and Cyber-Physical Systems. Many of my PhD works have been published in top design automation conferences, including DAC, ICCAD, ICCD. Check out my google scholar here.

📝 Selected Publications
End-to-end Uncertainty-based Mitigation of Adversarial Attacks to Automated Lane Centering
Ruochen Jiao*, Hengyi Liang*, Takami Sato, Junjie Shen, Qi Alfred Chen, Qi Zhu
- Analyze the impact of dirty road patch attack across the ADAS pipeline, and developed a method to quantitatively measure the perception uncertainty under attack.
- Conduct experiments on both public dataset and LGSVL. The results demonstrate that our approach can significantly improve the system robustness over the original OpenPilot implementation under adversarial attacks, reducing lateral deviation by 55% ~ 90%.
Security-Driven Codesign with Weakly-Hard Constraints for Real-Time Embedded Systems
Hengyi Liang, Zhilu Wang, Ruochen Jiao, Qi Zhu
- Incorporate weakly-hard constraints on resource-stringent distributed systems, conduct control analysis and schedulability analysis that account for task deadline misses. Develop meta-heuristic multi-objective optimization algorithm to improve system security, fault-tolerance and control performance.
Addressing Extensibility and Fault Tolerance in CAN-based Automotive Systems
Hengyi Liang, Zhilu Wang, Bowen Zheng, Qi Zhu
- Identify the metrics for measuring extensibility, fault tolerance and latency that can be captured by the model-based design (MBD) paradigm; present a simulated annealing based algorithm to search the design space, e.g. task allocation and scheduling, and analyze their trade-offs.
Delay-aware design, analysis and verification of intelligent intersection management
Bowen Zheng, Chung-Wei Lin, Hengyi Liang, Shinichi Shiraishi, Wenchao Li, Qi Zhu
- Develop a delay-tolerant protocol for intelligent intersection management that can ensure liveness under bounded commnucation delay.
- Model and implement our protocol in the SUMO traffic simulation suite with the extension of modeling communication delays.
- Verify the safety and liveness properties of our protocol by building more abstract timed automata models and leveraging UPPAAL verification tool.
