The Donohue Lab

Research Interests

I am a community ecologist and like to use experimental approaches to answer questions about the factors that regulate the structure, stability and functioning of biological networks. The overarching aim of my research is to further our understanding of how key elements of global change alter the functioning and stability of ecosystems.

An important goal of my research is to bridge the gaps between theoretical, empirical and applied ecology. My field research focuses mainly on aquatic ecosystems (both marine and freshwater), although more recently my approach to research combines experimental and observational work in the field, laboratory experiments using multitrophic microbial communities and in silico experiments on simulated model communities.
