My research focuses on how and why populations fluctuate in abundance across time and space and the implications of human-driven global changes, particularly climate change, habitat loss, and light pollution. I blend analyses of spatiotemporal datasets, quantitative modeling, and field experiments. Aspects of population dynamics I am especially interested include boom-or-bust fluctuations (population cycles) and the spatial synchrony of fluctuations in abundance. Forest-defoliating moths have been my main study organisms in recent years, but my studies have focused on a wide range of arthropods and host plants.
