Ph.D., University of Wisconsin - Madison

I am a 5th year Ph.D. student in the Electrical and Computer Engineering department of the University of Wisconsin - Madison, advised by Professor Kassem Fawaz at Wi-Pi and Security and Privacy Research Group at UW-Madison (MadS&P). My research interests focus on protecting user data privacy and building cyber-physical system for road user safety.

Previously, I investigated the privacy of mute buttons in video conferencing apps, including Webex, zoom, etc., on various desktop operating systems. Before that, I designed and implemented a pedestrian-to-vehicle authentication system based on pedestrian mobility verification using commercial mobile devices. I also implemented a crowd-sourcing pedestrian data collection app to tracking user’s daily walking behavior traces. Currently, I’m working on smartphone-based pedestrian road-crossing prediction to avoid potential traffic conflict through pedestrian motion tracking.
