After completing a Health Research Board 4-Year PhD at Trinity College Dublin I was awarded a Craig-Dobbin Newman Postdoctoral Fellowship in Mental Health Research by University College Dublin to study with Professor of Psychiatry, Kevin Malone. In 2013, I joined Professor Jonathan Mill’s Psychiatric Epigenetics Group at the University of Exeter as a Research Fellow. In 2015, I was appointed Lecturer in Biomedical Science at the University of Exeter Medical School and started an independent research programme examining the role of epigenetic mechanisms in Major Depression and Suicidal Behaviour. In autumn 2018, I returned to Ireland I took up the position of Assistant Lecturer at the School of Biological and Health Sciences, Technological University Dublin.

Research and Academic Interests

My research is focussed on studying gene regulation mechanisms of complex diseases, with a special interest in major depression and suicidal behaviour. The main research interests of the group are: (1) the role of epigenetic variation in major depression, suicidal behaviour and inflammatory-related disorders, 2) the role of non-coding RNA in the brains of depressed suicide completers; (3) the identification of molecular biomarkers of depression and suicidal behaviour. My research has been supported by a NARSAD young investigator grant award from the brain and behaviour research and Newman’s Craig-Dobbin Fellowship.
