SENIOR RESEARCH ASSOCIATES
JULIA BUXTON
Julia is based at the Department of Criminology at the University of Manchester after success in a British Academy Global Professorship grant application. The grant funds four years of research that will variously examine the impact of Brexit on illicit drug markets in the UK, and the extent to which drug policy reform in other countries has enabled a wider diversity of stakeholders to engage with drug policy processes. Previously Julia was Professor of Comparative Politics in the School of Public Policy at the Central European University, Budapest and was Senior Research Officer at GDPO 2013-2014. She researches on narcotic drug markets, with a specific focus on the inter-relationship between illicit drug economies, conflict, peacebuilding, and economic and democratic transitions. She has a particular interest in the impacts of counter narcotics strategies on gender, social justice and development. In addition to a number of GDPO policy reports, her drug related publications include The Political Economy of Narcotics (Zed, 2006), the edited collection The Politics of Narcotic Drugs (Europa 2010), ‘Opportunity Lost: Alternative Development in Drug Control’ in J. Tokatlian (ed) Old Wars: New Thinking, (Libros Zorazal, 2010); ‘A History of Drug Control’ in P. Keefer and N.

AXEL KLEIN
Axel is currently working on maritime security in the Gulf of Guinea as the Project Coordinator for the Support to West Africa Integrated Maritime Security (SWAIMS) project. He had prviously been working on the development / security nexus as a Team Leader and expert for the European Commission funded Cocaine Route Programme. With projects in West Africa, Latin America and the Caribbean, the programme was designed to tackle transnational organised crime and drug trafficking. The challenge was to direct partners away from seizures to in depth investigations, and in constructing an accountability framework.
Working with law enforcement and judicial authorities has been the unintended consequence of a long standing interest in drug issues and particularly the trans-cultural dimension in the spread of substances, habit and policy responses. Axel’s publications have looked at the policy environment (Drugs and the World, 2009), the tensions between cultural phenomenon and international prohibitions (Caribbean Drugs: from criminalisation to harm reduction, 2004), and the development dimension (The Khat Controversy: stimulating the debate on drugs, 2007). In addition, he has been working on the behavioural complex conventionally captured under the label ‘addiction’ and the range of interventions and treatments, an interest he continues to pursue as editor of the journal Drugs and Alcohol Today and is a member of the Global Initiative on Transnational Organised Crime network of experts.
Research Associates
ROSS EVENTON
Ross Eventon has been researching conflict, development and drug policy for over a decade. He has worked as a consultant for international organisations, research institutes and governments, and his writing has been published in outlets such as Le Monde Diplomatique and Al Jazeera. He holds an MA in International Relations from Webster Graduate School, and a BSc in Economics from the University of York. He is currently a Phd candidate at the Universidad del Rosario in Bogota, Colombia.
ALLAN GILLIES
Allan currently holds the post of ESRC Global Challenges Research Fund Fellow at the School of Social and Political Sciences, University of Glasgow. His project is titled, ‘Illicit Drug Economies, Governance and the Security-Development Nexus in the Global South: a Case Study of State-Narco Networks in Post-Transition Bolivia’. As such, the project engages with debates around the relationship between illicit drug economies and sustainable development, and the future of international counterdrug policy. This builds on Allan’s PhD research, examining interactions between the Bolivian state and the drug trade in the context of an escalating US ‘war on drugs’ in the Andes (1982-1993). Moving beyond the conventional assumptions of ‘drugs, violence and instability’, the thesis reveals how the drug trade became interwoven with informal forms of governance, political order and processes of transition.
Allan has also completed research for the Scottish Government’s Justice Analytical Services, Drug Research Team on growth of new psychoactive substances (NPS) in Scotland, including prevalence of use, supply chains, associated harms and user groups. Publications from this work have informed the Scottish Government’s research agenda around this topic.

This involvement gave rise to his co-authorship in a number of peer-reviewed journal articles:Treatment expectations and satisfaction of treatment-refractory opioid-dependent patients in RIOTT, the Randomised Injectable Opiate Treatment Trial, the UK’s first supervised injectable maintenance clinicsand Methodology for the Randomised Injecting Opioid Treatment Trial(RIOTT): evaluating injectable methadone and injectable heroin treatment versus optimised oral methadone treatment in the UK.
