The unifying theme behind all of my research is adding spatial movement to ecological and evolutionary processes. I develop hypotheses about the role of relative movement in ecological systems and the spatial patterns that develop when different parts of the natural system move in different directions or with different speeds relative to each other. I test these ideas using a mixture of theoretical modeling and highly replicated experimental microcosms with a strong emphasis on fitting mathematical theory with experimental data. I work at the boundary between scientific disciplines and collaborate with a diversity of scientific researchers studying problems related to animal migration, climate change, extinction, spatial spread, range limit dynamics, spatial evolution, habitat fragmentation, and thermodynamic niche modeling.
