One of the greatest challenges facing environmental biologists is to predict how the loss, over-harvesting, or invasion of one species will impact other species in the community. All species are linked through complex webs of interdependence. These interactions include feeding relations (food webs), mutualisms, facilitations, competitive interference, behavioral modifications, etc.

I work collaboratively with network theorists, computer scientists, and other field ecologists, and use a combination of approaches, to better understand the broader ecological impacts of biodiveristy loss and species invasions.
