In Memoriam

Activités de recherche et de formation

Benoît GELLER has an expertise in safety and security for wireless networks.

His work aims at protecting wireless communications against environmental interference and intentional attacks for the benefit of the French Ministry of Defense.

He has a strong experience in mobile communications systems. He works on the optimization of network resources from the physical layer to the application layer : information theory and coding (finite fields algebraic error correcting codes, turbo and LDPC, cryptography, ...), bayesian inference, security, scheduling, iterative and cross-layer solutions.

His results are applied to difficult contexts such as the doubly-selective underwater acoustic channel, or the energy-constrained Internet of Things (IoT) / Sensor network case, for which he has accumulated a good experience on practical architectures in different projects.

He has been involved in several European projects (Mast AIDA, Medea+ INCA, Medea+ MIDAS, Newcom++,Horizon 2020 Bridges, MarTERA Bioglider) and has also been in charge of many industrial projects. He has published about 100 international papers and has pended 4 international patents.
