Research and Practice Interests

Spatial population dynamics, metapopulation ecology, dispersal, plant insect-interactions, ecological modeling

I am broadly interested in ecology, and I have addressed questions ranging from the production of methane by animals under anthropogenic control, to statistical ecology, and interpreting biogeographical patterns. However, my main research interests focus on spatial population and community ecology. I am interested in understanding the consequences of movement of individuals among spatially segregated populations and the mechanisms affecting dispersal. I attempt to answer these questions using theoretical, experimental, and empirical perspectives.

Much of my research focuses on the Rocky Mountain Apollo Butterfly Parnassius smintheus. I am investigating factors affecting movement among populations and the consequences of local extinction and recolonization. More information is available on the alpine butterfly research site.
