Johan graduated in Applied Physics from Delft University of Technology, The Netherlands in 1991, and obtained a PhD in Earth Sciences from the Free University, Amsterdam, The Netherlands in 1997 on Tides in a Salt-Marsh. He worked on sediment transport and morphodynamics in the North Sea at the Institute for Marine and Atmospheric Research, Utrecht University, The Netherlands for six years, and moved subsequently to Manchester Metropolitan University, UK as a research fellow funded by The Liverhulme Trust. He joined Cefas in 2004, and has worked on the development and application of numerical models of waves, tides, sediment transport, transport and behaviour of planktonic stages of native and non-native species, transport of marine litter, and biogeochemistry and lower trophic level marine ecosystem dynamics. His work on biogeochemical modelling focused on anthropogenic impacts and management scenarios of, for example, riverine nutrient loads and large-scale marine renewable energy generation.
Johan has been a member of the OSPAR-Intersessional Correspondence Group on Eutrophication Modelling since 2006 and a member of the Executive Committee of the National Partnership for Ocean Prediction since 2015. He has convened the Open Session on Coastal and Shelf Science at the European Geosciences Union (EGU) since 2008, has been Secretary for Coastal and Shelf Seas in the Ocean Sciences Division of EGU since 2009, and Deputy President of the OS Division of EGU since 2014. He is Cefas Principal Investigator on several NERC-Defra research projects, and co-supervises PhD students.
