Philippe Van Cappellen (He/Him)

Dr. Philippe Van Cappellen is a Professor of Earth and Environmental Sciences and the Canada Excellence Research Chair Laureate in Ecohydrology. He leads an interdisciplinary research team focusing on water quality and ecosystem health, from local to global scales.

His research portfolio includes soils, rivers, wetlands, lakes, aquifers, coastal ecosystems, and urban water systems. Van Cappellen combines laboratory studies with field observations and modelling to develop a predictive understanding of the coupled hydrogeological, geochemical, and biological processes that regulate water chemistry and aquatic ecosystem functions, and how these respond to human pressures, including ongoing climate change. His work further includes the environmental fate and transport of a range of trace elements and contaminants (metals, hydrocarbons, microplastics), the calibration of geochemical (paleo)proxies, and the development of new water quality sensors and nature-inspired mitigation technologies. His model applications cover spatial and temporal scales ranging from molecular interactions at cell-mineral-water interfaces to the global cycles of carbon and nutrients.

Van Cappellen’s work addresses key challenges in water security and ecosystem management. He is active at the science-policy interface by providing guidance and models to boundary organizations that translate scientific findings for decision-makers. He regularly works with municipalities, conservation authorities and communities. By contextualizing emerging contaminants, salinization, eutrophication, and greenhouse gas emissions, he helps people recognize the importance of water quality and ecosystem services.
