As an invertebrate pathologist, my research program focuses on pathogens that cause chronic disease in beneficial insects

and arthropods that are used for biological pest control. I am particularly interested in microsporidian pathogens, having studied

them in predatory mites, lady beetles and lacewings. Recently classified as fungi, microsporidia are spore-forming pathogens

that often cause sub-lethal effects and reduce host fitness.

Current and past research projects include the ultrastructure and pathology of entomopathogenic microsporidia, host-pathogen

and host-parasitoid-pathogen interactions, host specificity of microsporidia , the effects of microsporidia on host fitness, and

epizootiology of insect diseases.
