My research interest are the biology and ecology of thrips in flowers and the foraging behaviour of bees. I have kept honeybees for many years and run courses for beginner beekeepers. My latest book on "Plants for Bees" is a comprehensive guide to the plants that benefit the bees of the British Isles. I have also published "A Colour Guide to Pollen Loads of the Honey Bee". I am currently a council member of the International Bee Research Association, a Fellow of the Royal Entomological Society, a Life Fellow of the Cambridge Philosophical Society and a Fellow of the Linnean Society.
