Climate change, nitrogen deposition, species interactions, food webs, community ecology.
I am broadly interested in understanding what determines ecological community structure and ecosystem functioning. My research primarily focuses on how indirect species interactions (i.e., ecosystem engineering, trophic cascades), drivers of global change, and environmental filtering affect species abundances and therefore community structure. In turn, I am interested in how ecological communities influence ecosystem functions and the services that ecosystems provide for humans. I use field experiments and modeling to determine the causes of community structure and the consequences for ecosystem processes. I employ both independent and collaborative approaches to my research, and in particular, I enjoy mentoring young scholars to prepare the next generation of ecologists.
