Sreejith Sreekumar

Biography

I am a CNRS researcher at the Laboratoire des Signaux et Systèmes (L2S), CentraleSupélec since February 2025. My research lies at the intersection of information theory, machine learning, mathematical statistics and quantum information science. Current topics of interest include study of distributed statistical inference problems under constraints, estimation of information & divergence measures, quantum hypothesis testing & estimation, privacy & security, and wireless communications.

I obtained my Ph.D. from the Electrical and Electronic Engineering Dept. at Imperial College London in 2019. Then, I spent a few years as a postdoctoral associate at the School of Electrical and Computer Engineering, Cornell University, and at Institute for Quantum Information, RWTH Aachen University. I obtained my Masters degree in Communications Engineering from Indian Institute of Technology Bombay and Bachelors degree in Electrical Engineering from National Institute of Technology Calicut.
