About
I am a postdoctoral scholar at the ProperData Center and the University of California, Irvine. I completed my PhD in Computer Science at the University of Virginia (UVA) in 2023 with a year spent at the University of California, Los Angeles (UCLA), advised by Prof. Yuan Tian.
My interests broadly include research in Security and Privacy, Internet-of-Things, and Human Computer Interaction with applications to smart systems (AI/ML) and public policy (law & policy). Specifically, I focus on bridging the gaps between computing applications’ behaviors and user perceptions/preferences, informing secure and privacy-respecting designs for future smart systems.
