My research investigates the mechanisms and drivers of diversity and richness patterns in ecological and biogeographical contexts. In many respects, they are driven by interactions among and between species and environmental influences. I examine such factors at multiple spatial and temporal scales to provide a broader understanding of how dominant influences shift and interactions change. This has led to a diverse set of projects and collaborations whereby I use models to test hypotheses and quantify the effects of the environment on species. I am particularly interested in non-volant small mammal community dynamics and disease ecology and geography.
