She has a BA(hons.) and an MA from Athens University of Economics and Business and a PhD in Econometrics and Social Statistics from the University of Manchester and has held posts in a number of universities in Greece, the United Kingdom and the United States.

Rebecca Thompson is a Senior Lecturer in Criminology at Nottingham Trent University. Her research focuses upon household burglary, anti-social behaviour and police-academic collaboration. Much of this involves working with external partners, for example the East Midlands Policing Academic Collaboration (EMPAC). Rebecca graduated with a PhD in Criminology in 2014. Prior to this, she worked for a police force in the UK (with a specific remit around crime reduction and community safety) before being awarded a Vice-Chancellor's Scholarship to undertake doctoral study. Since her PhD, she has held research and teaching positions at a number of academic institutions. Nick Tilley is a Professor in the UCL Department of Security and Crime Science, Emeritus Professor of Sociology at Nottingham Trent University and an adjunct professor at the Griffith Criminology Institute in Brisbane. His academic work has been devoted to developing and delivering theoretically informed applied social science. Specific interests lie in evaluation methodology, the international crime drop, problem-oriented policing and situational crime prevention, about all of which he has published extensively. He was awarded an OBE for Services to Policing and Crime Reduction in 2005 and elected a Fellow of the Academy of Social Sciences (FAcSS) in 2009.
