Much of my research is aimed at understanding what drives the success – or failure – of populations. This is done with an appreciation for the influence of spatial structure of the environment, temporal variation in environmental conditions, and the potential mismatch between evolved traits and conditions brought about by anthropogenic changes to the environment. Two main directions of this research have been 1) the interaction of life history adaptations and environmental change and 2) the influence of spatial structure of the environment and animal movement on population success.
