Chunyi Peng

I am an Assistant Professor in the Department of Computer Science and Engineering at the Ohio State University. I received my Ph.D in Computer Science at University of California, Los Angeles in 2013. Prior to UCLA, I had worked as an associate/assistant researcher in the Wireless and Networking Group at Microsoft Research Asia (MSRA) between 2005 and 2009.

My research interests are in the broad areas of mobile networking, system and security, with a focus on 3G/4G mobile networks, wireless networking, mobile sensing systems, and network security.

There is always opening for strongly self-motivated students who aim at academic excellence in mobile networking and systems in my lab. Students who are interested in mobile networking and systems, especially on 4G mobile networks and beyond, software defined networking (SDN), network function virtualization (NFV) and software defined radio(SDR), mobile security and mobile sensing (wearable and visible light communication). Solid networking background and network programing are mandatory.

This year (2017), in addition, I am particularly looking for one or two students who are dedicated to 5G research and have strong network programming/hacking experience (love to do so).

Prospective students please read the note first.
