Matt is a Senior Lecturer in Law and the Co-Founder and Director of Sussex Terrorism and Extremism Research Network (STERN).

Matt specialises in counter terrorism; criminal justice and legislative approaches (and reform) in the context of terrorism; international and regional legal frameworks for the countering of transnational terrorism; the implementation of international law, such as counter terrorism treaties and Security Council resolutions, in the domestic legal systems of States across different regions of the world (with a particular focus on substantive crimes and extraterritorial criminal jurisdiction); terrorist financing; terrorist incitement; extradition and mutual legal assistance; and related crime, such as transnational organised crime.

Matt has acted as an independent expert legal advisor on counter terrorism at the United Nations, a role which includes: providing legal advice to the United Nations on the international legal framework for the countering of terrorism and review of national counter terrorism legislation; and providing recommendations and assistance to governments on legislative reform and drafting and good practice guidance on issues relating to substantive crimes; extraterritorial jurisdiction; terrorist financing; terrorist incitement; human rights and countering terrorism; and international cooperation, such as mutual legal assistance and extradition. Matt also contributes to high-level international conferences on counter terrorism.

Matt is an Expert Member of the Education for Justice (E4J) initiative of the United Nations Office on Drugs and Crime (UNODC), which was developed as a result of the Doha Declaration on integrating crime prevention and criminal justice into the wider United Nations agenda, to address social and economic challenges, and to promote the Rule of Law at the national and international levels, and public participation. The Declaration, which was adopted by the Thirteenth United Nations Congress on Crime Prevention and Criminal Justice in 2015 recognizes the fundamental importance of universal education for children and youth, for the prevention of crime, terrorism and corruption, as well as for sustainable development. E4J is an innovative and comprehensive educational approach designed to support the integration of crime prevention and other rule of law aspects into all levels of education. At the university level, it aims to facilitate and promote teaching and research on issues related to UNODC mandate areas, including anti-corruption, organized crime, human trafficking, migrant smuggling, terrorism prevention, cybercrime, criminal justice and arms trafficking, as well as on integrity and ethics.

Matt has worked with the Terrorism Prevention Branch and the Organised Crime Branch of UNODC to deliver the first research project under the E4J mandate on the topic of identifying and countering the linkages between terrorism and organised crime. Matt has also implemented this research into draft teaching materials, which are intended to be integerated into tertirary-level education globally.

Research projects:

Matt is currently co-principal investigator (in collaboration with Dr John Jupp) on a project for the Terrorism Prevention Branch and the Organised Crime Branch at the United Nations examining the linkages between terrorism and organised crime.  

Matt is currently the lead of a research project at Sussex Law School on "Empirical analysis of State legislative responses to countering international terrorism". The project is comprised of a team of D.Phil. researchers at Sussex Law School and several experts around the world, including Russia, Africa and Canada. The aim of the project is to collect and examine the practice of States from all regions of the world in the countering of terrorism in terms of criminalisation and the extent to which provision is made for extraterritorial jurisdiction, particularly in the fulfilment of regional and international multilateral treaties and United Nations Security Council resolutions. A further consideration is mutual legal assistance and extradition. The project also aims to assess the extent to which there exists patterns, trends, similarities and disparities in State practice and the extent to which such practice complies with international law, and how counter terrorism responses could, if at all, be made more coherent and cooperation enhanced in combatting terrorism in the future. 

In 2014, Matt was appointed as an expert by the British Institute of International and Comparative Law to work on a two year project examining British influences and contributions on international law from a contemporary viewpoint, reviewing various international legal issues over the period of 1915 to the present day ( Matt's role was to undertake original and significant research in Britain's influence on the creation, development and enforcement of the laws of war and the punishment of war crimes, starting in 1915 to the present day period.

A number of controversial international legal questions, which during the twentieth century had become of greater importance than ever before in the modern history of international law, had to be critically analysed, including: (1) what type of conduct constituted violations of the laws of war and could such violations be treated as crimes under international law? Could they be conceptualised as ‘war crimes’? (2) Did such violations give rise to individual criminal responsibility? (3) Which States, if any, were permitted to try and punish violations committed by the enemy? (4) What extraterritorial criminal jurisdiction, as a matter of international law, was applicable over such violations? (5) Could the actual perpetrators be tried and punished (including after hostilities had ended); did this extend to include high ranking State officials and even Heads of State who order, instigate or fail to prevent such violations? (6) Did high ranking State officials have immunity from foreign criminal jurisdiction and could such immunity be removed? (7) Could perpetrators be tried by international courts and tribunals, in addition to national courts?
