I am interested in the ecology of estuaries, lagoons and intertidal systems. My primary research interest lies in understanding the roles of dominant species in structuring ecosystems and communities and predicting the consequences of their losses or shifts in range. These are important areas in modern marine ecology as several key species are affected by human activities and changing climates. The information gained is pertinent to developing fundamental ecological theory and to the management of coastal systems.
