Overview

My research focusses on estuarine and coastal geomorphology, biophysical interactions in mangrove and saltmarsh ecosystems, and the impacts of global change on landscape dynamics and ecosystem functioning. I am interested in whether the ecosystem services provided by coastal wetlands can be maintained under projected climate-change scenarios and anthropogenic interference.

Before moving to the University of Exeter, I worked as an Assistant Professor at Utrecht University where I conducted research and teaching in the fields of coastal and fluvial eco-morphodynamics. Previously I was also based at the University of Southampton where my research focussed on unravelling the interactions between estuaries, inlets and open coasts. Furthermore, at the University of Bordeaux in France, I worked on developing predictions of sea level rise impacts on salinity intrusion and sediment budgets in estuaries.

I obtained my PhD from the University of Waikato in New Zealand studying decadal scale dynamics of tidal basins and the effects of biophysical interactions.

I am working at Geography in Exeter since June 2019. Current projects involve a combination of numerical modelling, field data and remote sensing and focus on the resilience of coastal systems that are particularly sensitive to environmental change impacts, with the goal to inform sustainable management strategies.
