My research focuses on how and why populations fluctuate across time and space. I blend analyses of spatiotemporal datasets, quantitative modeling, and field experiments. I am particularly interested in understanding the factors influencing the spatial synchrony, cyclicity, and severity of forest-insect outbreaks.
