My current research addresses ecology of native bees in natural and agricultural systems. I am interested in the major stressors on health and how these interact, with a focus on pathogens, pollen and nectar sources, plus impacts of landuse and exposure to pesticides. I am carrying out long-term surveys of native pollinators to assess changes in diversity and abundance, particularly bumble bee species. I am also interested in fundamental and applied aspects of insect-plant interactions, especially those that can inform biointensive, reduced-risk management strategies for pests and conservation of beneficial species.
