Currently on leave Fall 2025-Spring 2026. I am an associate professor in the ECE Department at the University of Wisconsin – Madison, where I am also affiliated with the Computer Sciences Department. I serve as ECE’s inaugural associate chair for research. I received my Ph.D. from the CSE department at the University of Michigan. I currently lead my own research group: WI-PI.
My research interests primarily include the security and privacy for users interacting with their devices, with emphasis on voice interfaces, privacy policies, malware detection, data privacy, and wireless security and privacy. My overall research objective is to bring effective, practical, and usable security and privacy protection to the masses especially in the emerging computing paradigm of the Internet of Things. In the past, I made research contributions to software systems as well as wireless communications and networks.
