The goal of my research program is to integrate concepts from population, community, and disease ecology to understand how environmental change interacts with antagonistic and mutualistic species interactions to shape the abundances, distributions, and diversity of plant and animal species.  The following three sections highlight my current research interests.

Current research projects:

Natural enemy effects on demography, assembly, and diversity of plant and animal communities

Natural enemy effects on defensive traits and the ‘costs of fear

Novel pathogens and climate effects on continental populations
