Mary Wells

Mary Wells is a Professor in the Department of Mechanical and Mechatronics Engineering. She is also the Associate Dean of Outreach in the Faculty of Engineering at the University of Waterloo.

Professor Wells’ research focuses on the development and manufacturing of advanced metallic products used in the transportation sector. This involves developing mathematical models of the manufacturing processes used to make the metallic products, as well as understanding the microstructure and property changes that occur in the material. A materials final properties and structure depend on the process or manufacturing history such as thermal and deformation conditions. The mathematical models developed help manufacturers design casting and deformation processes that optimize a metal’s microstructure.

Professor Wells and her colleagues are working on the development of new processes to create laminate or clad metallic products via casting or deformation. The product resulting from these process are ones where the products surface will have different properties from its core, for example, a surface that is designed for corrosion and a core that is tailored for strength.
