Monique Laurent is senior researcher at CWI within the research group Networks and Optimization, with a part-time appointment as full professor at Tilburg University. She received her PhD degree in Mathematics at the University Paris Diderot in 1986. Before joining CWI in 1997, she has held research positions at CNET (French national center for telecommunication studies) in 1986/88, and from 1988 at CNRS (French national center for scientific research), affiliated with Ecole Normale Sup\’erieure in Paris from 1992. She was a Humboldt fellow at the University of Bonn in 1991/92 and had visiting positions at Yale University, IASI-CNR in Rome, and Tokyo Institute of Technology.
Monique Laurent investigates optimization problems arising in quantum information. In particular, she develops optimization methods aiming to quantify the advantage of entanglement in non-local games. Currently she is interested in designing efficient approximations based on polynomial and semidefinite optimization to approach the quantum value of non-local games and lower bound the amount of entanglement needed to realize quantum correlations.
