About Me
I am a Ph.D. student in the Department of Computer Science at Purdue University, advised by Dr. Z. Berkay Celik in the PurSec Lab. My research focuses on making emerging extended reality (XR) systems more usable, reliable, and privacy-preserving for everyday users.
I design and evaluate secure interaction techniques for mixed reality (MR) headsets, such as group pairing mechanisms that combine eye and hand-tracking–based localization, and study them through in-lab user studies. I also investigate how 3D user interface properties (e.g., overlapping or transparent objects and visual blind spots) can cause unintended interactions or expose more information than users expect, and develop design guidelines to reduce these risks.
In recent work, I have examined what low-resolution GPU performance metrics in XR may reveal about user activity (for example, application type or scene complexity) so that platform providers can harden their systems and adopt more privacy-aware telemetry and system designs.
