Dr Deirdre Healy ( is a lecturer in Criminology.  She obtained her primary degree in Psychology and Philosophy from Trinity College Dublin and then completed her doctorate at the UCD Institute of Criminology.  Her thesis explored the influence of psychological, social and criminal justice factors on desistance from crime.  She subsequently moved to NUI Galway to work on a study of attrition in rape cases.  Following this, she was employed as a research officer in the Centre for Criminological Research, University of Sheffield on the “Sheffield Pathways out of Crime Study.”  In 2008 she returned to UCD to take up an IRCHSS Post-Doctoral Research Fellowship at the UCD Institute of Criminology, during which, she conducted the Crime, Desistance and Reintegration Study, which involved a long-term follow-up of the sample interviewed for her doctoral research.  The study provides a detailed account of pathways to, and from, desistance and identifies the psychological and social processes involved in these transitions.  The project constituted the second phase of the first prospective study of desistance in Ireland and will be one of a small number of international studies of this kind.  Deirdre has also written a book The Dynamics of Desistance: Charting Pathways through Change, available now from Willan Publishing.

Dr David Doyle is an Irish Research Council (IRC) Postdoctoral Research Fellow at the UCD Institute of Criminology and a Research Associate of School of Social Work and Social Policy, Trinity College, Dublin. David read History and Politics at University College Dublin where he graduated with BA and MA degrees, before completing his doctorate at the National University of Ireland, Galway. A previous recipient of an IRCHSS doctoral scholarship, his PhD thesis, Sexual Crime and the Formulation of the Criminal Law Amendment Act 1935, investigated the incidence and prosecution of reported sexual crime against children in the formative years of the Irish state and provides a critical analysis of the law governing child sexual abuse in twentieth century Ireland. In 2010, David returned to UCD to work on a UCD NACD Study of Drugs and Health in Irish Prisons. Following this, he was employed as a Postdoctoral Research Fellow in the School of Social Work and Social Policy, Trinity College, Dublin, working with Dr Eoin O’Sullivan, on aspects of coercive confinement in the independent Irish state

David has been recently awarded an IRC Postdoctoral Research Fellowship and an IRC New Ideas Award to further his research on capital punishment in post-independent Ireland. Working under the mentorship of Professor Ian O’Donnell, the objective of this interdisciplinary project is to analyse capital punishment in post-partition Ireland, and investigate whether the progress to abolition in the respective jurisdictions of Northern Ireland and the Irish Republic was territorially idiosyncratic or influenced by European values and international human rights law. His other research and teaching interests also include criminal justice history, sexual offences, coercive confinement, and the criminalization/decriminalization of suicide.

David is also currently in the process of writing a monograph, provisionally entitled Capital Crime and Punishment in the Two Irelands, 1922-2001: Contexts, Comparisons and Contradictions. His most recent publication (with Ian O’Donnell) is (2012) “The Death Penalty in Post-Independence Ireland”. Journal of Legal History, 33 (1): 65-91.
