My research interests are in the ecology of coastal marine systems, with particular focus on sedimentary ecosystems, such as salt marshes and tidal flats. Since the start of my research career, I have been interested in understanding the link between individuals (e.g. behaviour), populations (demography), and communities (assembly).
Most recently, I have been interested in evaluating linkages between ecosystems (cross-boundary spatial flows of resources and biota) and elucidating ecological and management implications. I have a fascination for marine invertebrates, but enjoy studying all types of organisms.
My research methods typically involve (i) intensive sampling to observe and quantify patterns, (ii) detailed and rigorous experiments in the laboratory or field to test hypothesized processes underlying observed patterns, and (iii) development of mathematical models to integrate the knowledge that we have accumulated and assess the relative importance of processes on population, community or ecosystem dynamics. I welcome the involvement of students with a keen interest in learning experimental and/or mathematical ecology.
