Abstract
My primary research question is, why are species distributed non-randomly in the environment; that is, why do diversity gradients exist? This is a complicated question and requires the integration of a wide range of disciplines. One thing that is clear is that scale matters; explanations for diversity gradients at one scale cannot be applied to other scales. Until recently my major focus has on larger scales, ranging from sub-continental to global patterns. Here the single most important problem is working out how effects operating in ecological time and effects operating in evolutionary time are linked. We are pursuing this link by focusing on the relationship between current climate and historical patterns of climate change. Given that we are moving into a period of rapid global climate change, it is critical that we understand what aspects of climate drive diversity, and how organisms will respond when these variables change in time. In fact, I think we already have a descriptive answer to this question, at least at the global scale. Sorting out the mechanism(s) underlying the empirical relationships between diversity and climate, on the other hand, is a bit more of a challenge, and an emphasis of my research is to identify the most likely mechanisms that explain how climate operates on diversity both now and in the past. This requires information about both contemporary and paleo-climates. It has also become clear that a complete understanding of diversity gradients requires explicit evolutionary data, so another component of my research program is incorporating phylogenetic data into analyses of species richness.

I have recently begun to move into the field of community phylogenetics, with a particular interest in the influences of biogeographic processes on local-scale patterns. In this work the focus is not so much on species richness but on the role of evolutionary history on contemporary community composition and interactions between species' traits and environment.
