Tim Barraclough was born in Bradford, West Yorkshire, and was educated at Bradford Grammar School, and the Universities of Cambridge and Oxford. His DPhil research used large-scale phylogenetic data to look for correlates of diversification in birds and flowering plants. Moving to Imperial College London's Silwood Park campus in 1996, he worked first on the molecular systematics of tiger beetles, before establishing his own group with a Royal Society University Research Fellowship followed by a Lectureship in 2003. He has worked on a wide range of different animals, fungi, plants and bacteria and used a range of different methods ranging from theory and computation, through field work and systematics, to studying evolution 'live' in the laboratory. In 2012, he was awarded the Bicentenary Medal of the Linnean Society for a scientist under the age of 40.
