About

I am an assistant professor at the University of Alabama. Previously, I was at the University of California (Irvine/Los Angeles) and University of Virginia. I completed a PhD in Computer Science in 2023, advised by Professor Yuan Tian.


My research interests broadly include Security and Privacy, Human-centered Computing, and Emerging Technologies, with applications to smart systems (AI/ML) and public policy (law & policy). Specifically, my work focuses on usable security and privacy for emerging technologies (e.g., IoT, AI, XR) and the implications of technology and policy. The overarching goal is to bridge the gaps between computing applications’ behaviors and user perceptions/preferences as well as inform secure and privacy-respecting designs for future smart systems.
