Research Interests

I conduct research under 4 themes that are related in their aim of understanding the dynamics of sediments and nutrients in the coastal environments, and how these contribute to controlling state changes in the physical environments. These themes are (1) dynamics of the swash and surfzone; (2) beach morphodynamics; (3) nutrient dynamics in estuaries; (4) tidal inlet and estuarine morphodynamics.
