I am a technician with training in environmental sciences, and have experience with various chemical, physiological and biological analyses of soils, plants, invertebrates and micro-organisms.
Main tasks and work fields are:

  • Plant and microbial soil-community experiments
  • Soil invertebrate experiments
  • Teaching: Biodiversity and Ecological Fieldwork (1st year Biology undergraduates)
  • Teaching: Coastal and Marine Ecosystems Fieldwork (2nd year Biology undergraduates)
  • Greenhouse coordination

Main techniques are:

  • Molecular microbial ecological analyses, with PCR and DGGE
  • Nutrients in plants and soils
  • Chemical and physiological plant-traits
  • Invertebrate determination

For more information on projects see the links below:

Prof. Hans Cornelissen

Prof. Rien Aerts


I also enjoy working with nature in my free time, and zoom in on life with with macro-photography and Invertebrate determination.
