PhD candidate in Aquatic Ecotoxicology: Faculty of Science – Institute for Biodiversity and Ecosystem Dynamics. The Institute for Biodiversity and Ecosystem Dynamics is one of eight research institutes of the Faculty of Science at the University of Amsterdam. The institute covers a wide range of subjects in both fundamental and applied research. Our scientific studies aim at a better understanding of the dynamics of ecosystems at all relevant levels, from genes to climate change, using a truly multi- disciplinary approach.

Project description

Innovation of ecotoxicological water quality assessment

The assessment of the chemical and ecological status of freshwater ecosystems each comes with specific scientific and practical limitations. Furthermore, to register the absence of compounds comes with high costs for water authorities. In this PhD-project we aim therefore to innovate ecotoxicological water quality assessment and to integrate this into a program for Smart Integrated Monitoring (SIMONI). We aim to incorporate passive sampling and effect monitoring with bioassays into ecotoxicological water quality monitoring and to identify hazardous compounds by means of effect-directed analysis (EDA). The designed Smart Integrated Monitoring program or model will pose an alternative for the current Water Framework Directive (WFD) monitoring. This PhD-project will improve the scientific quality, and meanwhile reduce the costs of ecotoxicological water quality assessment.

Five work packages are foreseen:

  1. passive sampling;
  2. optimization and validation of bioassay batteries;
  3. optimization and validation of bioassay trigger values;
  4. effect-directed analysis and
  5. toxicity traffic light modelling and design of a Smart Integrated Monitoring model.


  • MSc in Aquatic Ecology, Aquatic Ecotoxicology, Aquatic Toxicology or Environmental Chemistry;
  • experience with experimental approaches relevant to the project, such as passive sampling, bioassays, effect-directed analysis and environmental hazard & risk modelling is recommended;
  • experience with laboratory and/or field experiments, preferably with macroinvertebrates;
  • interest to combine to theory, laboratory and field studies, and data analysis;
  • skills with statistical analysis is appreciated;
  • ability to work on a multidisciplinary topic in a multidisciplinary research team;
  • driving license.
