Research Interests

Daithí's research interests are in law and technology. In particular, he works on audiovisual media law, legal issues in the creative industries, the 'sharing economy', data and open data, and Internet infrastructure and domain names. He has further interests in constitutional and administrative law, in language policy, and in approaches to legal research.

He is a co-director (leading on legal and IP issues) of Future Screens NI (R&D project, part of the AHRC creative economy clusters programme, 2018-22), and was formerly co-investigator at CREATe, the centre for copyright and new business models in the creative economy (funded by AHRC, ESRC and EPSRC, 2012-17), and a member of the ESRC Centre for Competition Policy (East Anglia).

In autumn 2018, Daithí held an Arthurs Visiting Fellowship at Osgoode Hall Law School, Toronto, working on 'disruption' to law and the future of cities; this work was further developed in a contribution (on mobility data) to a 2019 data governance workshop at Tilburg, and a guest lecture on the sharing economy at Newcastle. His work on this theme continues in 2020, including a lecture at the Institute of International and European Affairs (Dublin) in January, and visiting seminars at Southampton and Maynooth.

His book Medium Law (Routledge, 2017) explores the application of ‘medium theory’ (including the work of Harold Innis and Marshall McLuhan) to differences between media, and how technological definitions and associated changes have legal and regulatory consequences. It has been reviewed in the Entertainment Law Review (29(3), 2018) and the European Journal of Law and Technology (2018)

He will be a co-author of a leading textbook in the field, Information Technology Law (also Routledge), from its next edition, and co-edited a collection on privacy law in the UK (The Campbell Legacy, 2018). He is co-editor of the forthcoming book Executive decision-making and the courts: revising the origins of modern judicial review (Hart, 2021) and is co-editing a book for Oxford University Press on the philosophical foundations of cyberlaw.

Daithí's research on technology and media law has been published in various journals, including Legal StudiesJournal of Media LawCommunications Law, and the International Journal of Law and Information Technology. His most recent work includes a study of ranking and reputation systems (co-authored with Mathias Siems, in the Modern Law Review), and an article on intermediary liability and responsibilities, published in Information and Communications Technology Law.

Beyond his primary work on law and technology, other recent work includes an assessment of legal education in Northern Ireland in light of Brexit (with Mark Flear, in Law Teacher), a report on how legal research is evaluated in the UK, published in a book comparing practices across Europe, an analysis of the official status of languages in the UK and Ireland, in the Common Law World Review, and ongoing work with TT Arvind (University of York) on constitutionalism and empire (including a forthcoming article in the Northern Ireland Law Quarterly on self-rule movements in Ireland and India).


Daithí is a panelist for the UDRP dispute resolution mechanism for Internet domain names, provided by the Czech Arbitration Court, and is a member of the Irish government's Open Data Governance Board. Consultancy work has been carried out for Google and, via the Scottish Centre for International Law, the OECD.

He is book reviews editor of the International Journal of Law and Information Technology, and a member of the editorial board of Communications Law. He served for four years as a co-editor of the Dublin University Law Journal. He now sits on the advisory boards of the Society for Computers and Law and the Information Law & Policy Centre, and was subject section convenor for media and communications law at the Society of Legal Scholars (where he is now a member of the Research Awards Committee). He is currently an external examiner at the University of Leeds, the London School of Economics & Political Science (LSE), and University College Cork (UCC). In addition, he is a member of the ESRC Innovation Caucus, the AHRC Peer Review College and the UKRI Future Leaderships Fellows Peer Review College, and has served on the Irish Research Council's Outer and Inner Assessment Boards, and as a reviewer for the ESRC and for Innovate UK.


In 2019-20, Daithí convened and taught the stage 3 (final year) optional module in media and information law for undergraduate law students, and contributed to the School's intellectual property modules - stage 3 LLB and copyright in the digital environment (LLM) - which are led by Prof. Ronan Deazley. From September 2020 he will teach on the new LLM Law and Technology, leading the new modules on Regulating Innovation (semester 1) and Regulating Digital Communications (semester 2).

He has also served as the module coordinator for the public law modules on the LLB degrees and the LLB (Senior Status): Constitutional Law in Context (semester 1) and Rights and Accountability (semester 2). In previous posts, he has taught subjects including entertainment law, e-commerce, international IP law, and various aspects of media law.
