Maren leads the Soil Ecosystem Dynamics Research Group with an international team whose work focuses on climate change and the impact of climate change on plant and soil ecosystems, restoration of marginal/degraded lands, and sustainable agriculture (permaculture, intercropping, agroforestry practices, organic farming). The goal of this research group is to enhance our knowledge of the environmental processes that take place in plant and soil ecosystems. By doing so, we hope to further understand how to use natural, managed and restored ecosystems to help mitigate and adapt to climate change. In addition to field and laboratory work (in Canada and abroad), her research team also uses novel and advanced techniques that help to understand future changes in soil-plant interactions under global change scenarios. She teaches courses in forest ecosystems and management, soil ecosystem dynamics and tropical ecosystems.
