Iain is an Associate Professor in the Department of Zoology and Entomology who specialises in various aspects of biological control of weeds. He has worked as an exploratory entomologist surveying for new potential biological control agents on a number of invasive alien plant species, including cactus weeds and tropical trees that have invaded island ecosystems. Iain is also interested in the origin of invasive populations of plants and how this impacts the success of biological control and has been involved in a number of projects that have used genetics to determine where alien populations come from. Other aspects of Iain’s work include host specificity testing and improving how we test the safety of potential agents and assess the risks of releasing new agents.
