I am an Assistant Professor in the Department of Computer Science at North Carolina State University (NCSU). I am also a member of the Networking Research Group at NCSU. I received my Ph.D. degree in Computer Science from Michigan State University.

I am recruiting self-motivated and hard-working graduate students who are interested in computer networks, Internet of things, and/or computer and network security. Students with a relatively strong mathematical background are preferred. If you are interested, please first go through this page, and then send me an email.

Research Interests

My research interests lie in the broad areas of Networking, Internet of Things, and Security, with a focus on network measurements and modeling, RFID based systems, activity recognition, and user/device authentication.
