Many of my research projects center on determining the relative importance of evolutionary processes versus ecological factors as drivers of community structure. To answer this question, I am working to identify the possibility of coordinated stasis in fossil communities, make inferences about the ecological requirements of a species and identifying what hierarchical patterns exist in ecological networks. Investigations of body size have become a key component of this research because body size is a proxy for a swathe of functional life history traits and thus provides a simple metric for assessing the dynamics of ecological networks and phenotypic response of communities to environmental change. Examples of specific studies I have undertaken in this area include identifying the importance of population subdivision as a driver of community diversity, assessing how extinction risk is connected to the energetic requirements of a species and quantifying the relative import of biotic interactions as a mechanism for evolutionary change.
