research overview

  • Prof. Varanasi's recent research has been on long-standing as well as modern problems of establishing information-theoretic limits or fine approximations thereof of networks whose understanding would lead to a fundamental redesign of cellular networks and that model a broad range of practical scenarios spanning different topologies and settings including cellular, interference and multihop (mesh, wimax) networks with general messaging, multiple-antenna terminals, feedback, relaying and channel uncertainty models. Communication, signal processing algorithms and coding techniques for such networks have also been of interest.


  • Information Science and Engineering, theoretical foundations of processing (communicating/compressing/storing) data over networks and extracting information from data, including information theory, theory of communication, wireless communications, coding and system optimization, signal processing and statistical/machine learning theory and their applications
