Profile
Research Description
Vinod Prabhakaran received his Ph.D. in 2007 from the
Electrical Engineering and Computer Science Department,
University of California, Berkeley. After postdoctoral
work at Coordinated Science Laboratory, University of
Illinois, Urbana-Champaign and Ecole Polytechnique
Federale de Lausanne, Switzerland, he joined Tata
Institute of Fundamental Research, Mumbai in 2011. His
research interests are in information theory, wireless
communication, cryptography, distributed signal processing
and communication.
My research is in the area of information theory and
in particular in its applications to communication
and cryptography. Information theory originated
as a mathematical formulation of the problem of
communicating a source (e.g., what a microphone picks
up) over a channel (e.g., wireless). Significant success
has been achieved in understanding this point-to-point
problem and it forms the theoretical underpinnings of all
modern communication systems. However, the natural
generalization of the point-to-point problem to network
settings presents several significant challenges. My
research aims to answer many of these - limits of reliable
communication in communication networks, distributed
source coding and computation in networks, secure
(multiparty) computation.
