Louise Millette has been a Ph.D. professor in the Department of Civil, Geological and Mining Engineering at Polytechnique Montreal since 2002 and was its director until June 2021. It was the deplorable state of the Rivière des Prairies and the hope of making a difference that led her to civil engineering and environmental protection.

Ms. Millette catalyzed Polytechnique's commitment to sustainable development (SD). In 2004, she wrote her first environmental policy and in 2019 created the SD Office. As a result of these actions, Polytechnique was awarded STARS Gold accreditation in 2019. It is working to integrate SD into the training of engineers.

Ms. Millette's involvement in several organizations has earned her several awards and honors, including the titles of Knight of the Order of Montreal and Fellow of Engineers Canada, as well as awards from the Minister of Education and Higher Education and the Quebec Business Women's Network.
