Biography

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. He is the core developer of Lethe, an open source high-performance and high-order implicit CFD solver (https://github.com/lethe-cfd/lethe) based on the open source DEALII platform (www.dealii.org). He has published more than 50 peer-reviewed journal articles or conference abstract.

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 from Polytechnique Montréal, 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.
