I am a fourth-year PhD student at HCI Institute in Carnegie Mellon University, advised by Chris Harrison in the Future Interfaces Group. My research explores the intersection of Human-Computer Interaction, Sensing, and Robotics. I explore non-anthropocentric machine perceptions for human-centered future computing. I presented papers at prestigious computer science conferences such as ACM CHI and UIST and received two Best Paper Honorable Mention awards at CHI. Formerly, I was a member of UC Berkeley BAIR AUTO Lab, working with Ken Goldberg. I interned at Apple AI for Robotics (2024, 2025) and Meta Reality Labs (2023). I obtained MS from KAIST School of Computing, advised by Geehyuk Lee at KAIST HCIL.
