Pr Blais expertise lies in the development, verification, and validation of high performance digital models for fluid mechanics, heat transfer, and complex multi-physical and multi-scale phenomena. His research interests are in computational fluid mechanics (CFD), reacting flows, granular and solid-fluid flows, topology optimization as well as high-performance computing on distributed high-performance architecture and on GPU. He is the core developer of Lethe, an opens source high-performance and high-order implicit CFD solver ( based on the open source DEALII platform ( He has been an active collaborator of the CFDEM project (, an open-source platform for granular and solid-fluid flows, since 2013.

Pr Blais is Assistant Professor at École Polytechnique since 2018. Before this, he was a Research Officer with the Automotive and Surface Transportation Portfolio of the National Research Council of Canada (NRC AST) where he has carried out extensive work on multiphysics modelling using the finite element method. He has earned a B. Eng. in Chemical Engineering, a Grande École Engineering Diploma from ENSTA Paristech, a master in Fundamental Fluid Mechanics from ENSTA and a Ph.D. in Chemical Engineering from Polytechnique Montreal. Pr Blais is a Vanier Graduate Scholar (2012-2016) and has received the Govenor’s General gold academic medal for his thesis work on numerical modelling of multiphase flows. He has also received the best thesis award from Ecole Polytechnique (2017) and the North American Mixing Forum (2016-2017). Pr Blais has also received other recognitions such as the Da Vinci Profile of Ecole Polytechnique (2012) and the Master Île-de-France international Scholarship (2011-2012).
