I lead Kew’s research on the ecological function of plant and fungal chemicals, the interactions that plant chemicals mediate between plants and other organisms and the potential to use plants sustainably for enhancing ecosystems and improving horticulture.
My research focuses on the chemistry that mediates pollinator-plant and plant-pest interactions. This includes how plant chemicals affect insect behaviour, health and ecosystem function, for example through exposure to toxins or inadequate nutrition and the potential for plants to provide environmentally benign alternative pest control in smallholder agriculture. My work is funded by BBSRC, National Science Foundation (US), European Union, Peter Sowerby Foundation and the McKnight Foundation.
I hold a dual role as Professor of Plant Chemistry at the Natural Resources Institute (University of Greenwich).
