• My research interests are all aspects of software and systems security. In particular, my research focus is designing and implementing advanced bug sanitization and mitigation techniques to protect operating systems and user applications in existing and emerging areas (e.g., autonomous driving, drones) by leveraging compiler, fuzzing, and AI-based techniques.
