Philippe Maisonneuve holds a master's degree in fluvial ecology from the Université de Montréal. He participated in three years of sampling aboard the research vessel Lampsilis of the Université du Québec à Trois-Rivières.

He has developed extensive field experience, project logistics, data analysis, and knowledge of emerging issues related to water quality and aquatic environment integrity. He conducted an environmental assessment for the city of Trois-Rivières to map and budget a plan to analyze the impacts of untreated wastewater discharges on receiving environments. His expertise in aquatic ecology allows him to investigate the impacts of pollution sources beyond their point of emission and to contribute to the development of concrete strategies to improve the health of waterways.
