Dr. Ricardo Pereira joined the Cardiff Law & Politics School in October 2015 as Senior Lecturer in Law and was promoted to Reader in Law in August 2020. At Cardiff he is a member of the Environmental Justice Research Unit, the Centre for Crime, Law and Justice, the Centre for Human Rights and Public Law and the International Studies Research Unit, and his administrative and teaching roles have included Route Convenor of the LL.M. in International Commercial Law programme, Chair of the LL.M Exam Board, leader of the International Energy Law LL.M module and contributing to the teaching in the LL.B programme in EU Law and Company Law.

Prior to joining Cardiff he held positions in a number of other UK academic institutions, including Senior Lecturer in Law at the University of Westminster, Business School (2013-2015), Lecturer in Environmental Law at Imperial College London, Centre for Environmental Policy (2009-2012) and also taught in international environmental and natural resources law at Queen Mary, University of London and University College London (UCL). He holds a Ph.D. in Law (University of Essex), an LL.M. in Public International Law (City, University of London) an LL.M. in International Business Law (Queen Mary, University of London) and an LL.B. in Law (Federal University, Ufba).

His research interests lie primarily in international and European environmental law, energy and natural resouces law, European and transnational criminal law, environmental crime and law enforcement, as well as other sub-fields of public international law including international economic law, the law of the sea and human rights law. His monograph 'Environmental Criminal Liability and Enforcement in European and International Law', (Brill, 2015) assesses legal, theoretical and practical questions relating to the harmonisation of environmental criminal law in Europe and internationally, as well as the constitutional dimensions and effectiveness of transnational legal mechanisms aimed at combatting environmental crime. The book is widely cited in the 2018 United Nations Environment Programme's comprehensive study on environmental crime globally. More recently he co-edited 'The Governance of Criminal Justice in the European Union: Transnationalism, Localism and Public Participation in an Evolving Constitutional Order' (Edward Elgar, 2020) and is finalising a book on international natural resources law (in contract with Routledge) due to be published in 2021.

He has undertaken research and regularly gives advice to international and national organisations and NGOs, including the International Union for Conservation of Nature (IUCN), the United Nations Environment Programme (UNEP), the European Commission, the National Assembly for Wales and the Instituto Colombo-Aleman para la Paz (CAPAZ). He is currently a member of the IUCN World Commission on Environmental Law, on the advisory board of the International Community Law Review, on the guest editorial board of the Review of European, International and Comparative Environmental Law (2019-2021) and has previously acted as the book reviews editor for the European Energy and Environmental Law Review (2009-2012).
