Since starting research in 1968, Tony Cox has published over 150 research papers and 30 reviews and evaluations on a range of topics in atmospheric chemistry. His main contributions to the understanding of the chemistry of the atmosphere is through studies of kinetics and mechanisms of atmospheric reactions. His work led to many new insights into the atmospheric oxidation of sulphur dioxide and volatile organic compounds, the formation of peroxyacetyl nitrate and the chemistry of alkoxy radicals, which are central to photochemical oxidant pollution. He has also demonstrated the formation of novel unstable halogen compounds which become significant at low atmospheric temperatures and play important roles in the chemistry of Antarctic ozone depletion. He has contributed to numerous international assessments of tropospheric chemistry and stratospheric ozone depletion.

Michael Scott is currently the Moses and Mary Finley Fellow in Ancient History at Darwin College and an affiliated lecturer at the Faculty of Classics, University of Cambridge. He is the author of From Democrats to Kings (2009) and Delphi and Olympia (Cambridge University Press, 2010). His research concentrates on the roles of material culture in ancient Greek and Roman society. In addition, he is actively engaged in broadening access to, and engagement with, the ancient world through school talks, guest lecturing, writing for national and international newspapers and magazines, as well as presenting historical documentaries for TV in the UK, USA and Australia.

Layla Skinns is a Lecturer in Criminology at the Centre for Criminological Research, School of Law, University of Sheffield and formerly the Adrian Socio-Legal Research Fellow, Darwin College and Teaching Associate at the Institute of Criminology, University of Cambridge. She has conducted a wide array of research on topics such as crime prevention, drug users and the criminal justice system, restorative justice and, most recently, on policing in England, Ireland, Australia and the United States.
