Organisations

My research focuses on the complexities of coastal morphodynamics, related to bedform patterns (e.g., tidal sandbanks and sand waves) and barrier coasts. Of my particular interest is the link between autonomous dynamics and the response to human intervention, such as sand extraction. To understand these systems, I develop, apply and analyze mathematical models that describe the water motion, sediment transport and bed evolution.
