About

Hongjun Choi is a leading researcher in the security and safety of cyber-physical systems, with a primary focus on robotic vehicles (RVs) such as drones and ground rovers. His work addresses critical vulnerabilities at the intersection of the cyber and physical worlds, pioneering methods to detect, analyze, and recover from attacks that exploit these systems' unique operational environments. Choi's most influential contribution is his foundational work on detecting attacks against robotic vehicles, which has garnered 184 citations and established a key framework for understanding how RVs can be compromised despite their robustness against natural disturbances. He further advanced the field by introducing the concept of "Cyber-Physical Inconsistency" vulnerabilities, which target safety checks like crash detection through malicious environmental manipulation. His research extends to real-time software-based recovery from sensor attacks and forensic analysis through replay with what-if reasoning, enabling investigators to reproduce accidents and determine root causes. Through these contributions, Choi has become a pivotal figure in ensuring the resilience and trustworthiness of autonomous robotic systems, with his work directly informing both academic research and practical security implementations in the rapidly evolving field of autonomous vehicles.
