Phil’s research has focussed on the biological and ecological role of plant chemicals and understanding how these compounds can be used to support sustainable agriculture. This work includes research on pollen and nectar chemistry to determine their role in pollinator behaviour and health and behavioural ecology, natural pest resistance in crops to identify breeding traits and the optimisation of pesticidal plants (botanical insecticides) as environmentally benign and affordable alternatives to synthetic insecticides. Phil has led major research and development projects won through competitive bids to programmes including: Innovate UK, Newton, DFID, BBSRC, DEFRA, McKnight Foundation, European Union (ACP Science and Technology programmes), USDA and NSF (USA). Other smaller grants have been won competitively through the Science Foundation of Ireland, Higher Education Funding Council for England, Bill and Melinda Gates Foundation and the Millennium Science Foundation (Uganda). Phil’s research has been published in more than 150 international journal articles, books and books chapters including recent papers in Science, Current Biology, Ecological Monographs, Journal of Ecology, Frontiers in Ecology and the Environment and Functional Ecology. His international scientific role is represented through positions on the editorial boards of journals including Subject Editor at the Bulletin of Entomological Research, Regional Editor of Biopesticides International and the Editorial board of Crop Protection and People, Plants Planet. He is a Fellow of the Royal Entomological Society and Member of the British Ecological Society
