Biography: 

Marney Isaac, Assistant Professor and Canada Research Chair in Agroecosystems & Development, conducts interdisciplinary research on plant strategies and the nutrient economy of agroecological systems while concurrently charting the human dimension of agroecosystem management. Her research provides mechanistic insights into the ecological principles, nutrient cycles, and plant-soil interactions that govern the structure and function of agricultural landscapes, with particular attention on identification of strategies for environmental services, system resilience and sustainable livelihoods. Her research approach makes use of a diverse set of technical tools and employs various temporal and spatial scales: from mechanistic manipulative trials at the rhizosphere scale to large agroecosystem dynamics. She also supervises an international research program investigating agrarian management networks and environmental governance, with an emphasis on understanding innovation in large social-agroecological systems. She has published widely in environmental science, agronomic and multi-disciplinary journals including Agriculture, Ecosystems & Environment, Agronomy for Sustainable Development and Ecology and Society.
