He is a permanent member of the EPROAD research unit (EA 4669), specifically working within the SIMaPE team (Simulation and Engineering of Materials and Processes for the Environment) since January 2012. His academic affiliation falls under the Materials and Process Engineering (IMaP) theme of the research unit. Christophe Marie specializes in modeling granular media using the discrete element method (DEM) . His research focuses on simulating the behavior of granular materials to understand physical phenomena involved in fluidization operations, including heat transfers. The objective of his work is to optimize industrial processes for particle emptying, drying, energy production, and neutralization of fluidized bed effluents. His primary research involves modeling multi-physical processes with emphasis on the hydrodynamic behavior of fluidized granular media, examining both fluid effects on particles and particle concentration effects on flows. He incorporates convective and conductive heat transfers in his models. Complementing this theoretical work, he also conducts experimental determination of heat and momentum transfers in granular media to validate his digital simulations against real-world cases. Research Keywords: Simulation in granular media, Discrete element modeling, Fluid-structure interactions, Fluidization, Heat transfers, Multi-physical processes Christophe Marie has contributed to academic supervision, notably co-supervising Sherko Alkawarzi's PhD thesis in 2014. Within the SIMaPE team, his work supports the broader mission of developing sustainable materials and processes that reduce energy consumption, promote recyclability, and utilize renewable resources while maintaining industrial efficiency. The SIMaPE team, which Christophe Marie is part of, focuses on the entire lifecycle of materials from development to end-of-life, with particular attention to the product/process relationship and product quality analysis. Their research spans special concrete engineering, agroadjuvants, agropolymers, and 100% bio-sourced agrocomposites, all developed with sustainability as a core objective.
