We use a variety of tools – observational field studies, manipulative experiments in the lab and field, ecological and simulation modeling, population genetic, and genomic approaches – to forge a deeper understanding of the ecology and evolution of forest insects, microbes and trees, particularly in the context of biological invasion.  Principal themes of our research include:

Novel associations and communities in forest and plantation ecosystems

Patterns and consequence of global connectivity in invasive populations

Community variation and landscape genetics in the beech bark disease pathogen complex

Community consequences of native insect range shifts

Biological control of Emerald ash borer: Understanding drivers to predict outcomes

Plant-insect interactions; biodiversity of insects and fungi in forest ecosystems
