Lawrence W. Sherman is a world-renowned criminologist whose work on the prediction of crime has revolutionized policing and criminal justice. As the founder of the new field of 'evidence-based policing', he has led the creation of new learned societies for that field in Britain, USA, Canada, Australia and New Zealand. He has lectured on the use of prediction and prevention of crime to governments in over thirty countries, and is widely known for his proposals to base better prevention of violence on better prediction, from the under-identified 'hot spots' of crime to the over-prediction of serious offenders. David Allan Feller holds a PhD in the History and Philosophy of Science from the University of Cambridge, as well as a law degree from Georgetown University Law Center in Washington DC. His work at the University of Cambridge and the University of Manchester, particularly regarding the use of dogs as models in evolutionary and genetic science, has created new discussion in both Darwinian studies and concepts of cultural influences in biology. Most recently, he has lectured in Law and Science at the University of Cambridge, discussing how law and science combine to guide notions of the future.
