Marine researcher, photographer, diver, available for work or consultancy contracts.

Welcome to my website! I am a marine ecologist passionate about sustainability, biodiversity, taxonomy and how human-induced changes are affecting marine ecosystems. For my PhD in marine ecology I investigated changes in gelatinous zooplankton (“jellyfish”) communities in Dutch coastal waters by analysing long-term datasets and performing field surveys as well as experiments.

After my PhD I worked for a while at a sustainable fishing NGO, before returning to science where I now specialise in research focused on zooplankton diversity, ecology and monitoring. At NIOZ I investigated the impact of Blue Energy production on zooplankton through monitoring and experiments. Currently I am working on implementing imaging and machine learning techniques for zooplankton research and monitoring using an underwater microscope.

Experienced in organising research projects, research cruises and monitoring surveys, analysing long-term data, experiments, and species identification/taxonomy of benthos as well as zooplankton and fish. For more information please see my curriculum vitae and publications.

I maintain two other websites:

  • zooplankton.nl, which provides information and imagery related to Dutch zooplankton, their diversity and ecology.
  • vliegerfotograaf.nl, which showcases my aerial photos taken from a kite.
