I am the Chief Technology Officer (CTO) of Nexcepta, where I oversee a broad portfolio of cutting-edge R&D efforts in wireless communications, networks, security, 5G/6G, machine learning, data analytics, and computing (ranging from theory and algorithm design to software and hardware implementation). Previously, I was a Research Professor at the Virginia Tech National Security Institute and the Director of Networks and Security at Intelligent Automation/BlueHalo. I am also serving as a Visiting Research Professor in the Department of Electrical and Computer Engineering at the University of Maryland, College Park, and an Affiliate of the Virginia Tech National Security Institute. I received my Ph.D. in 2007 from the Department of Electrical and Computer Engineering at the University of Maryland, College Park, where I worked as a Research Assistant at the Institute for Systems Research (ISR). Later, I was a Visiting Assistant Research Scientist with ISR. I also worked as a Postdoctoral Fellow at the Department of Electrical Engineering and Computer Science at Northwestern University.
My research interests are in wireless communications, networks, security, machine learning, and 5G/6G systems (see Expertise). I published over 200 papers in these areas as of 2024 (see Publications). My work has also contributed to various commercial products such as deep learning-based radio platform, FPGA IP core for deep neural networks, social media analytics software, network emulation and software-defined radio (SDR) programming tools. My work has been cited as an ARO success story and transitioned to various Government and industry venues.
As part of my professional activities, I have organized and chaired conference tracks (IEEE PIMRC, IEEE GlobalSIP, and IEEE MILCOM), served in the conference organizing committee (IEEE GLOBECOM and IEEE MILCOM), organized and chaired several workshops (at IEEE CNS, IEEE ICNP, ACM Mobicom, and ACM WiSec), organized tutorials (at IEEE MILCOM and IEEE GLOBECOM) and invited sessions (at IEEE MLSP and WICON). I am an Editor of IEEE Transactions on Communications and an Editor of IEEE Transactions on Cognitive Communications and Networking. I was invited by academia, industry and government agencies to give talks and serve on panels in the areas of machine learning, wireless security, and 5G/6G. I have served on TPCs of major IEEE and ACM conferences and served as reviewer for major IEEE journals and transactions.
