On graduating in Zoology from the University of Leeds, David moved to Imperial College, London, where he gained his MSc in applied entomology. Research into the reproductive physiology of the sheep blowfly Lucilia sericata, begun at Imperial College, became the subject of his PhD thesis at Birkbeck College, London. David has published a number of papers on blowfly reproductive physiology and with Professor John Cloudsley-Thompson published on the molecular and physiological mechanisms of biological clocks.
As Head of Department, David has long experience of teaching biology. He has written articles covering fieldwork and biological education and is also author of many highly successful biology course-books for all levels. He was Editor of the magazine Countryside for fourteen years. Currently he is a freelance author and tutor in Cambridge and a panel tutor for the University of Cambridge Institute of Continuing Education. David’s continuing interests in developing programmes for the Public Understanding of Science include the Biology of Medicine and Evolutionary Theory. He communicates these interests through books, lectures and online to a wide audience in the UK and overseas. He is an elected Fellow of the Linnean Society and the Royal Entomological Society and an elected Member of the Royal Society of Biology.
