Biography Summary

Marios Ioannidis is a Chemical Engineering Professor and the Associate Chair for Undergraduate Studies at the University of Waterloo.

His research work involves understanding the performance of different classes of porous material in various engineering applications and how the macroscopic behaviour emerges from processes taking place at the pore scale. Professor Ioannidis’s research aims to improve the ability to engineer materials with desired macroscopic properties or to optimize a process for a specific class of porous media.

Conducted research on porous media transport addresses the characterization and modelling of the porous microstructure, specifically mass transfer from distributed sources in porous media. Professor Ioannidis is currently characterizing and modelling the structure of vuggy carbonate rocks, which are reservoirs for most of the world’s remaining hydrocarbon resources.

Capillary, wetting and flow properties of gas diffusion layers for Polymer Electrolyte Membrane (PEM) fuel cells, is also a component of Professor Ioannidis’s research. It involves measuring and explaining the complex capillary wetting and flow properties of gas diffusion layer (GDL) materials, so that predictive modelling of PEM fuel cell performance may be enabled.
