About me

I’m a Postdoc in the CopeNLU group at the Department of Computer Science, University of Copenhagen. I am also affiliated with the Pioneer Centre for Artificial Intelligence. Currently, I work with Prof. Isabelle Augenstein and Prof. Irina Shklovski on the ERC-funded ExplainYourself project, researching human-centred explanations for automated fact-checking.

My research in human-AI interaction is interdisciplinary and draws from artificial intelligence, human-computer interaction, and cognitive psychology. In my work, I examine the design and evaluation of explainable AI systems and how they can be designed to support human reasoning in complex decision-making tasks, such as identifying misinformation. My primary research interests are in eXplainable AI (XAI), human-AI interaction, fact-checking and explanatory reasoning.

I completed my PhD in the School of Computer Science and Insight Centre for Data Analytics, University College Dublin, supervised by Prof. Mark Keane and Prof. Ruth Byrne. My doctoral research examined the efficacy of counterfactual explanations in explainable AI, taking a human-centred approach, grounded in cognitive psychology, to explaining AI system decisions.

I hold a B.A. (Hons) in Psychology from Trinity College Dublin, and I worked as a research assistant in Trinity College Institute of Neuroscience prior to beginning my PhD. I also speak Irish (Gaeilge), the native language of Ireland (along with almost 2 million other people!).
