Our nematology research program focuses on the development of management strategies for plant-parasitic nematodes affecting high value horticultural crops. The overall goal is to identify sustainable nematode management practices and then to deploy these management practice targeting the biology of the nematode.

Current projects include the evaluation of grape rootstocks for root-knot nematode management, integrated management of root lesion nematode in raspberry, and genomic insights into plant-parasitic nematodes including the nematode microbiome.
