Research Interests
I study the persistence of species and communities in heterogeneous, fragmented, and disturbed landscapes; and what determines the diversity of communities in these landscapes. I use field surveys and experiments, laboratory experiments and theory. My current research is focused on 1) how environmental heterogeneity affects invasibility and extinction in communities, and 2) how landscape spatial structure and traits of species determine the structure and dynamics of communities.
