Research interests

I started at NIOZ as Senior Scientist in Coastal and Biophysical Oceanography in September 2017 after working at Cefas, a governmental research laboratory in Lowestoft, UK for 13 years. At Cefas, I created hydrodynamical model setups for GETM, restructured and extended the particle tracking model for GETM, developed a suspended sediment model for the coupled physical-biogeochemical model GETM-ERSEM, and contributed to the development of ERSEM. I applied these models to address scientific and managerial questions. I also gave scientific guidance to a team of numerical modellers. Before that, I worked as a post-doc at IMAU, Utrecht University on sediment transport and morphodynamics, and as visiting research fellow at Manchester Metropolitan University on wave-induced sediment resuspension.

My research interests are in modelling physical and biological material transport, biogeochemistry and ecosystem dynamics in shelf seas, in response to natural and anthropogenic influences.
