Dr. Mary Wells has extensively contributed to the science and engineering of materials processing, leading to improved understanding of the heat transfer and microstructure of metals. She has driven the development and validation of mathematical models, probed fundamental phenomena associated with heat transfer and microstructure evolution, and led design changes required to improve process/product quality. In 2015, she became the President of the Metallurgy and Materials Society of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM). Dr. Wells has also been an outstanding leader and role model in engaging and supporting women in engineering through her roles as Professor, Associate Dean, Dean, and Chair of the Ontario Network of Women in Engineering. Her leadership has contributed to an increase in the number of women in engineering in Ontario, and she has developed models of engagement that are offered nationally.
