Hans Helder

Dr. Hans Helder is an Associate Professor at the Laboratory of Nematology, Wageningen University & Research. His research focuses on nematode systematics, molecular diversity, and their roles in soil ecosystems. Key projects include developing molecular tools for nematode community analysis and studying plant-parasitic nematodes like Meloidogyne chitwoodi. His work bridges phylogenetics, ecology, and agricultural applications, emphasizing sustainable soil management.

Research interests span nematode phylogenetics, evolution of parasitism, and biodiversity assessment using advanced techniques like nanopore sequencing. Collaborations include Prof. Gerrit Karssen (Dutch Plant Protection Service) and academic partners. Publications highlight high-resolution monitoring of soil nematode communities and their responses to cover crops and plant pathogens.

Expertise includes Globodera (potato cyst nematodes), plant-parasitic nematode detection, and soil health indicators. His lab's contributions advance understanding of nematode-driven ecosystem processes and agricultural solutions.
