Dr. Marshall's research focus is advanced wireless systems. Current research topics include wireless sensors, cognitive radio and networking, and the spectrum policy implications of emerging technology. He has a particular focus on the problems of network scaling, dense wireless systems, the use of Dynamic Spectrum Access (DSA) to provide methods to address interference, front-end performance, and scaling in emerging dense wireless architectures, as well as decision and information theory application to distributed wireless networks.
Preston Marshall received his BS in Electrical Engineering and MS in Information Science from Lehigh University. He also obtained his Ph.D. in Electrical Engineering from Trinity College in Ireland. He holds a joint appointment as a Research Professor in the Department of Electrical Engineering at USC and a Division Director at the USC Information Sciences Institute. Previously, he was a Program Manager at the Defense Advanced Research Projects Agency (DARPA) for seven years, and developed research programs in cognitive radio, dynamic spectrum access, sensor networks, content-based and delay tolerant networks, and probabilistic computing. Dr. Marshall has authored and co-authored numerous papers, journal articles and book contributions. He recently authored "Quantitative Analysis of Cognitive Radio and Network Performance". He chairs the Executive Steering Committee of the IEEE International Symposium on Dynamic Spectrum Access Networks (DYSPAN) conference, and is track chair for the IEEE/AFCEA MILCOM 2011 conference. He is a member of the IEEE Communications Society.
