Research Interests

My research is primarily concerned with the behaviour and ecology of entomopathogenic nematodes and their use as biological insecticides. Current interests include competition, reproductive behaviour and signaling of nematodes; proteomic profiling of nematode infective juveniles; competition and coexistence of symbiotic bacteria and the services they provide for their nematode hosts; and biological control of insect pests including the large pine weevil (Hylobius abietis) in reforestation. I am also interested in the effects of climate change on pest insects. My research is funded by national and international funding bodies and involves collaboration with research institutions and end-users.
