B. Rousseau is a Senior Researcher at CNRS and the director of the French CNRS Research Group TAMARYS. His research focuses on the multi-scale modeling of thermal radiative properties in heterogeneous media using 3D digitalized images, with applications in heat exchangers, volumetric solar absorbers, and infrared heating.F. Enguehard is a Professor at the University of Poitiers. His research interests include radiative heat transfer in non-Beerian media, the interaction of radiation with sub-wavelength complex-shaped objects, and conduction-radiation coupling in heterogeneous media using stochastic modeling techniques.S. Foucaud is a Professor at the University of Limoges and leads the Ceramics under Environmental Constraints research axis at IRCER. Her research focuses on the development of ceramic materials for extreme conditions, such as high temperatures and aggressive environments. She is also a member of the scientific council of the CNRS INC.
