Biography

Romit Roy Choudhury is an Associate Professor of ECE at the University of Illinois at Urbana

Champaign (UIUC). He joined UIUC from Fall 2013, prior to which he was an Associate Professor at

Duke University. Romit received his PhD in the CS department of UIUC in Fall 2006. His research

interests are in wireless protocol design mainly at the PHY/MAC layer, and in mobile computing

at the application layer. Along with his students, he received a few research awards, including the

Sigmobile Rockstar Award, IBM Faculty Research Award, NSF CAREER Award, the Google Faculty Award,

best paper at Personal Wireless Communications conference, Hoffmann Krippner Award for Engineering

Innovations, etc. Visit Romit's Systems Networking Research Group (SyNRG), at http://synrg.csl.illinois.edu

Research Statement

Romit's research interests are in wireless networking and protocol design mainly at the PHY/MAC layer, and in mobile computing at the application layer.

In wireless networking, our research is focussed on exploiting physical layer (PHY) capabilities towards wireless protocol design, often on the software radio platforms.

In mobile computing, we envision mobile smartphones (and emerging wearable devices) as a convergent platform for sensing, computing, and communications.

Our goal is to integrate these three capabilities thereby enabling new classes of personal and collaborative applications and technologies.
