I am interested in the ecology and evolution of aquatic ecosystems. Food webs exhibit remarkable structural diversity, but how does this influence the functioning of ecosystems?
To predict how ecosystems will respond to global environmental change, we need to understand the processes that maintain food web diversity and functioning of ecosystems. This requires a more complete integration of ecology, evolution, and ecosystem science.My research has two main themes:
I. How do ecological, evolutionary, and anthropogenic processes structure aquatic food webs?
II. How does the structural diversity of food webs affect ecosystem functioning (i.e. the physical properties and biogeochemical cycling of aquatic ecosystems)?
I approach these questions using large scale mesocosm experiments, and a combination of comparative field surveys, modeling, and lab studies.
