Research

Baccelli's research is at the interface between mathematics (probability theory, stochastic geometry, dynamical systems) and communications (information theory, wireless networks, network science). * His work with P. Brémaud on the stationary-ergodic framework for queuing networks represents such networks as functionals of point processes on the real line. This led to mathematical tools which are now commonly used in applied probability and in the communication network literature. * Jointly with G. Cohen, J.P. Quadrat and G.J. Olsder, he contributed to the development of an algebraic theory for the dynamics of networks, the so-called (max, plus) algebra. This impacted several fields of engineering (network calculus) and mathematics (

tropical geometry In mathematics, tropical geometry is the study of polynomials and their geometric properties when addition is replaced with minimization and multiplication is replaced with ordinary addition: : x\oplus y=\min\, : x\otimes y=x+y. So for exampl ...

). * He is best known for contributions to

stochastic geometry In mathematics, stochastic geometry is the study of random spatial patterns. At the heart of the subject lies the study of random point patterns. This leads to the theory of spatial point processes, hence notions of Palm conditioning, which exten ...

. His results on the Poisson-Voronoi model, the Poisson-Shannon model, and the Poisson-Voronoi-Shannon model laid the foundations of the representation of communication networks as functional of point processes in the

Euclidean space Euclidean space is the fundamental space of geometry, intended to represent physical space. Originally, in Euclid's ''Elements'', it was the three-dimensional space of Euclidean geometry, but in modern mathematics there are ''Euclidean spaces ...

. This led to wireless stochastic geometry, initially developed with B. Blaszczyszyn, which is now commonly used in the communication network literature. * His current research interests are in stochastic geometry in high dimension, in the theory of stationary point processes, and in the mathematics of unimodular random graphs.
