Dr. Masoud Hosseinpoor is a Research Associate in Civil and Building Engineering at the Université de Sherbrooke (Canada), where he earned his Ph.D. and previously held a postdoctoral fellowship within the NSERC Industrial Chair on Fluid Concrete with Adapted Rheology. His research focuses on the rheology and multiscale characterization of cement-based materials, numerical simulation of concrete flow and pumping (CFD, DEM, and coupled CFD-DEM), stability, passing ability, and granular packing of self-consolidating concrete, 3D concrete printing, sustainable earth-based and bio-based concretes, nanocellulose admixtures, and machine learning for predicting and controlling concrete performance. He led the development of Canada's first large-scale concrete 3D-printing robot. He has written close to 40 peer-reviewed journal articles and book chapters in leading journals such as Cement and Concrete Research, Cement and Concrete Composites, Construction and Building Materials, and Materials and Structures, along with numerous oral presentations and papers at international ACI and RILEM conferences. He co-supervises M.Sc. and Ph.D. students, coordinates the university's concrete laboratory, and serves as a technical advisor to industrial and public-sector partners across Canada on applied projects ranging from tunnel pumping to precast and infrastructure concrete. He reviews for many journals in his field, is a member of ACI and CRIB, and works professionally in English and French.
