Professor of Process Engineering at the University of Lorraine. His research is in aerosol filtration, a subject he introduced to the laboratory in 1994 (The Laboratory Reactions and Process Engineering (UMR CNRS 7274)). His research focuses on the separation of liquid and / or solid (nano to micron dimensions) with filter media or other methods of separation and characterization of aerosols. His research interests include: areas of personal safety (respirators, safety filters), the environment (atmospheric particulate emissions) and methods (protection filter). He is board member of the ASFERA (French Association for Studies and Research on Aerosols), founding member and vice president of the French Society of Fluid Separations-Particles (SF2P).
