Research interests & activities

Broadly, my research concerns the influence natural enemies (insects and pathogens) on plant populations. This research is primarily in the context of biological control of weeds including, classical, augmentative, and bioherbicide approaches.  Currently, my research has a particular emphasis on biocontrol of thistle weeds of pasture.
