Denis Rodrigue obtained a B.Sc. (1991) and a Ph.D. (1996) in chemical engineering from Université de Sherbrooke (Sherbrooke, Canada) with a specialization in non-Newtonian fluid mechanics. In 1996 he moved to Université Laval (Quebec City, Canada) where he is now full professor. Since then, he has been an invited professor at the University of Guadalajara (Mexico), the Technical Institute of Karlsruhe (Germany), the University of Castilla-La Mancha (Spain), the University of Arts and Sciences of Hunan (China), the Technical University of Lodz (Poland) and Polytech Tours (France). His main research areas are in the characterization and the modelling of the morphological / mechanical / thermal / rheological properties of polymer foams and composites based on thermoplastics and elastomers. His main focus is related to polymer recycling and rheology.
