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). Assistant Professor of Process Engineering at the University of Lorraine, France. His research studies deal with the characterization of aerosols and their collection with different kinds of separators (fibrous filters, bubble columns, granular beds, etc.). Assistant Professor of Process Engineering at the University of Lorraine, France. Her research studies deal with the filtration of aerosols and dust explosions and are conducted using computational tools such as CFD codes. Assistant Professor of Process Engineering at the University of Lorraine, France. His research, conducted in the Reactions and Chemical Engineering Laboratory, focuses on filtration of solid and liquid aerosols by fibrous media.
