 I am looking for new Ph.D. and M.Sc. students to start work in 2019. My lab studies the ecology of plants and their natural enemies (herbivores and pathogens) in Ontario and elsewhere. Recent work has centred on the effects of insects and soil pathogens on non-native species, and whether damage depends on latitude, population isolation, and other factors. I’m also planning new projects studying factors setting northern range limits of invaders, and investigating herbivore tolerance of invasive species. Information on our research can be found at my home page:

We are a thriving department at a leading research institution, with excellent resources and many opportunities for interaction and collaboration. All graduate students are guaranteed a stable minimum income, currently $26,750 from a variety of sources, which provides for tuition (ca. $8500) and living expenses ($18,250). Additional support is available for research and conference travel. Information on application procedures and our tri-campus graduate program can be found at our grad student website, This year, we are inviting applications for Canadian M.Sc. and Ph.D. candidates and a limited number of foreign Ph.D. positions. Application are now open, and we will begin to review them in January 2019 for start dates in the summer or fall of 2019. Interested students should first contact me via e-mail:
