Teaching and research interests are primarily in the fields of coastal and coral reef geomorphology and management, with particular expertise in reef flat sediment transport and reef island development and stability, vessel wake dynamics and environmental effects, sand extraction from the coastal zone, coastal monitoring methodology and medium term beach change, high energy beach dynamics, and beach and intertidal flat water table responses. The integration of indigenous knowledge with geomorphic history of environments, and the application of geomorphology to environmental management are important themes.
