Analyses of social and human activities
-
The avalanche of digital data tracing social activities opens the way to combine data analysis and modeling with social science studies. Along this line, we study data representing human interaction or behaviour, or date pertaining to transportation (e.g., BSS or traffic on roads); in all these cases, the dynamics of the data (for instance of the networks uwed to represent them) is crucial and tailored methods are developed leveraging on methods in physics and/or signal processing.

La turbulence des fluides et le traitement du signal sont des domaines intimement liés. D'une part, les mesures expérimentales d'un écoulement turbulent, et les simulations numériques des équations de Navier-Stokes, ont bénéficié des techniques et développements de la science du signal. D'une autre part, la nécessité de prendre en compte l'aspect multidimensionel des grandeurs liées à la turbulence, et la volonté de construire des modèles aléatoires capables de rendre en compte des statistiques particulières observées dans les écoulements, est un territoire fécond pour le développement d'approches multivariées des signaux. L'équipe Sisyphe depuis longtemps s'attèle à développer ce domaine pluridisciplinaire.

Internet traffic and networks
-
The team has studied the statistics of the IP trafic over the Internet networks, both from modeling and experimental (monitoring) points of view. Results about the statistics of IP traffic were obtained (such models with Long Range Correlations) and pratical applications such as classifaction of traffic and host or anomaly detection were developed.

Physics of biological systems
-
We explore two different tracks in the physics of biological systems: an combined experimental and theoretical approach in the quest of new diagnostic tools of cancers thought the correlation between viscoelastic mechanical properties and pathology, and a theoretical study of non-linear synchronizations in organs and tissues.
