Biography

My long-term research interests focus on the ecological and coevolutionary dynamics of natural host-microbe interactions using theoretical and spatially explicit computer modelling, experimental and field studies and molecular approaches. While much of my career has centred on the population and metapopulation dynamics of plant-pathogen systems, I have also worked extensively on the ecological associations between native legumes and associated nitrogen-fixing soil bacteria (rhizobia). Such interactions provide an opportunity to address fundamental questions in community ecology, including the evolution of host specificity, shifts along the mutualism-parasitism continuum, impacts of plant-soil feedbacks on community structure, and geographic-scale patterns in soil diversity and symbiotic effectiveness.
