The central aim of my research is to elucidate the processes driving fluctuations in population abundance across time and space. I address theory that is relevant to conservation of native and beneficial insects as well as management of agricultural and forest pests. My approach blends field experiments, analysis of spatial data, and theoretical modeling.

My current research has four foci: 1) the role of multitrophic interactions and weather in the spatial synchrony and periodicity of forest-insect outbreaks; 2) the effects of climate change on the outbreak dynamics of forest-defoliating insects; 3) the ecological interactions driving the expansion or contraction of species’ range borders; and 4) the influences of landscape structure on plant-herbivore interactions.
