Since the 1930s, the Nematology research unit has developed experience in nematological research, especially in taxonomy, morphology and phylogeny. Currently, the group focuses on the taxonomy, phylogeny, morphology and biology of nematodes from natural and agricultural ecosystems including free-living, plant-parasitic, virus-vector families and entomopathogenic nematodes.

Research conducted on marine and brackish free-living nematode taxa is very limited at this moment, with a focus on the taxonomy, phylogeny and morphology of Desmoscolecida, Epsilonematidae and Draconematidae. Nevertheless, the group considers organising a yearly workshop on the identification of aquatic nematodes. Further, the group contributes (editor) to the World Database of Free-Living Marine Nematodes (NeMys).
