Projekte:

March 2021 - Present

  • Gravity field retrieval simulations with EPOS-OC for NGGM/MAGIC – Science Support Study and ESA Third Party Mission Study.
  • Support for development of Payload Data Ground Segment concept for the NGGM study.

March 2019 – February 2021

  • Development of SNAP pipeline in python for the calculation of land subsidence from SAR Sentinel1 images.

  • Modelled suspended particle matter in the Wadden sea using stacked ensemble machine learning methods.

  • Developed Flask based API for doing pre-processing for chemical and biological input components to the DFlowFM model.

  • Developed and deployed docker containers for Jupyter notebooks on Azure. These notebooks were for online courses at Deltares.

  • Developed a gradient boosting based machine learning model to predict overtopping at coastal structures.

December 2015-February 2019

  • Developed a river routing model to simulate the movement of surface runoff to oceans on a global scale. 

  • Constructed an interface that converts weather data from three different sources into a standard format and combines these into a single database. 

  • Constructed models to predict overtopping at coastal structures with OpenFOAM (IHFoam).

  • Trained feedforward and recurrent neural networks on river discharge data.
