His research addresses the following key areas: (1) How do plant invasions and their management affect native ecosystems? (2) What effects do single and combined multiple stressors (deer, earthworms and invasive plants) have on species and ecosystems? (3) How can we achieve improvements in the success of biological weed control? and (4) What determines the increased competitive ability of invasive plants?
