Cette recherche explore l'utilisation des résidus de bauxite, ou boues rouges, comme substitut aux matériaux routiers conventionnels au Québec. En conditionnant le résidu et en optimisant son incorporation dans l'asphalte, les travaux visent à réduire la dépendance aux granulats naturels, à réutiliser les déchets industriels, à diminuer les coûts et à prolonger la durée de vie des routes de six à dix ans.

This research explores using bauxite residue, or red mud, as a substitute for conventional road materials in Quebec. By conditioning the residue and optimising its incorporation into asphalt, the work aims to reduce reliance on natural aggregates, reuse industrial waste, lower costs, and extend road lifespan from six to ten years.

This research develops biodegradable “living” water filters grown from kombucha cellulose membranes. Unlike conventional plastic filters, these biofilters can self-defend against harmful microbes and self-repair when damaged. The work aims to create affordable, sustainable, and effective water filtration systems that reduce plastic waste while improving access to clean drinking water.

This research investigates phosphorus pollution in Lake Warner by comparing water movement and phosphorus transport through urban and forested landscapes. Forests naturally filter phosphorus due to slower water travel and greater infiltration, while urban runoff accelerates pollution. The study identifies how interventions such as rain gardens can reduce phosphorus loading into lakes.

This research addresses overheating in 5G base stations, where vertically mounted electronics create dangerous hotspots. By using passive vapor chamber cooling, heat is efficiently redistributed without added energy use. Experimental and modeling work shows vapor chambers improve reliability and sustainability, supporting faster, more stable 5G and future network infrastructure.

Bacteria can cause major industrial failures through metal corrosion, but most bacteria are harmless or beneficial. This research engineers protective bacterial strains to prevent corrosion by sealing cracks, forming biofilms, and outcompeting harmful microbes—transforming bacteria into a sustainable defense for metal infrastructure like pipelines, bridges, and buildings.

This research reinvents wastewater treatment by adapting circulating fluidized bed reactors—normally used in petrochemicals—to grow bacteria on small surfaces and efficiently remove waste. Mobile, trailer-mounted reactors provide high-performance treatment without large facilities, making them ideal for dense cities, remote communities, and overburdened systems.
