EducationBiodiversity Post-Doctoral Fellow, University of British Columbia. 2016 PhD, Queen's University. 2014 MSc, University of Calgary. 2007 BSc, Trent University. 2003 ResearchMy research focuses on interactions among species (biotic interactions) and the dynamics of species range limits. Much of my research is field-based; I conduct large- and small-scale experiments in natural environments to test and refine theoretical ideas in ecology and evolution that have practical conservation relevance. I am especially interested in adaptation in range-edge populations, interactions among flowers and their visitors, and the role biotic interactions play in shaping species’ geographic distributions.QCBS students Shannon Meadley DunphyPh.D.  Cole LarsenM.Sc.
