Daithí's research interests are in law and technology, with recent work addressing audiovisual media law, legal issues in the creative industries, the 'sharing economy', and data and open data. 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 (AHRC), and was formerly co-investigator at CREATe, the centre for copyright and new business models in the creative economy (AHRC, ESRC and EPSRC, 2012-17), and a member of the ESRC Centre for Competition Policy (East Anglia).

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 2019), an article on intermediary liability and responsibilities, published in Information and Communications Technology Law 2020, and a book chapter on personalisation and 'smart cities', forthcoming in a Cambridge University Press collection edited by Jacob Eisler and Uta Kohl.

Recently, Daithí has focused on 'disruption' to law and the future of cities, through an Eisenhower Fellowship, an Arthurs Visiting Fellowship at Osgoode Hall Law School, Toronto (autumn 2018), and recent presentations including on mobility data (Tilburg, 2019 and Maynooth, 2020), and on the sharing economy (Newcastle, 2019). His public lecture on the topic, at the Institute of International and European Affairs (Dublin) in January 2020, is available to watch.

His book Medium Law (Routledge 2018) 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. For reviews, see 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 (with David Mangan and Catherine Easton) on the philosophical foundations of cyberlaw.
