I am an assistant professor in the Computer Science Department at George Mason University. Before joining Mason, I was a postdoc at University of California, Davis where I worked with Dr. Prasant Mohapatra. I received my Ph.D. in Computer Science from North Carolina State University in 2012 where I was supervised by Dr. Rudra Dutta. I received the UC Davis award for excellence in postdoctoral research for 2015.

RESEARCH INTERESTS

The focus of my research is to make wireless networks and mobile systems more efficient, accessible, robust and truly pervasive. I am currently interested in the following topics -

Next-generation wireless networks, especially 60 GHz millimeter wave networks, visible light communications
RF sensing, mobile/wearable sensing for applications like healthcare and mobile interaction, drone sensing and networking
Cyber-physical systems, smart indoor spaces, Internet-of-Things and low-power networking
