In 2005, David moved to Cambridge to study Criminological research at Darwin College. During this time, he became interested in the relationship between alcohol and violence, specifically, in the way that social environments can mediate or prevent violent behaviour in intoxicated individuals. David’s PhD, entitled ‘Do flexible opening hours reduce violent crime? An evaluation of the Licensing Act (2003),’ capitalised on a large natural experiment in alcohol policy (the Licensing Act, 2003) which removed restrictions on alcohol trading times in the interests of preventing violence. Following his PhD, David worked as a research assistant on a project funded by the European Commission, ‘Strengthen transnational approaches to reducing reoffending (STARR)’. Here, he contributed to a series of systematic reviews investigating the effectiveness of behavioural interventions for reducing reoffending in offender populations.

David is a CEDAR postdoctoral research fellow. His research continues to explore how the social environment can affect health and wellbeing. He is interested in various aspects of applied intervention research, such as: the design of complex interventions (e.g. natural experiments), the measurement of environmental exposure in routine behaviour (using GIS, GPS, and accelerometer data), health inequity, and research synthesis methodology.

Within CEDAR David is currently working on the Commuting and Health in Cambridge study (led by David Ogilvie), which looks at the health impacts of the Cambridgeshire Guided Busway. In this project he is investigating how exposure to new transport infrastructures can be quantified, and how travel behaviour and health are related. In another CEDAR project, David is investigating how interventions to reduce physical inactivity are effective in different demographic groups. In other projects David continues to research prevention initiatives for reducing alcohol related harm.
