EducationResearchMy research gravitates around community ecology, plant ecology, mycorrhizal symbioses and soil fungi. I am interested in untangling the drivers of symbiotic, bipartite community assembly, with a focus on network-based mathematical tools to quantify their structural patterns. Using mycorrhizal symbioses as a model system, and network-based approaches as a tool, my aims are to (1) advance our understanding of this widespread and ecologically significant symbiosis and (2) provide empirical tests for theory related to assembly and dynamics of ecological networks. I thus see my research as one displaying a happy mix of question-based and system-based approaches (i.e. system-based research anchored by a strong theoretical background).QCBS students Hiba BenmohamedPh.D.  Béatrice Gervais-BergeronPh.D.  Elisa Bussing HudonM.Sc.
