Jurgen van Hal


I am working as an ecological research technician at the department of Ecological science. My current tasks and skills are:


Determination of invertebrates, incl. Collembola.

Breeding of various invertebrates

Teaching assistant 1st years course: field-entomology and lab-determination

Experimental work and field experiments

Setting up and maintaining diverse field, greenhouse and climate room experiments. These experiments include work with mesocosms, stable isotopes, plants, plant-litter, invertebrates, algae and micro-organisms.

Chemical and animal traits measurements

Diverse chemical analysis and animal-traits such as Nutrient analysis, fat-content, drought tolerance, inundation tolerance, upper thermal limit.


DNA isolation, PCR, high-throughput sequencing and microbial community analysis.


Histology of small invertebrates

Additional skills and useful hobbies

Allround microscopy

Maintaining technical and analytical equipment.

Macro and invertebrate photography

freediving (and scubadiving)
