Professor Guay’s research focuses on the development of new materials for the energy and environmental sectors. Professor Guay is interested in nanomaterials and metastable materials produced by mechanical grinding and pulsed laser ablation. He is particularly interested in the phenomena that occur at the surface of these materials and govern their reactivity at solid-liquid and solid-gas interfaces. These fields of interest are applied electrocatalysis, whether for fuel cells or electrolysis, and hydrogen storage. Professor Guay has extensive expertise in the field of materials characterization, and is behind a number of experimental developments enabling in situ characterization of electrode materials.
