Profile
I am an AI and Natural Language Processing researcher and technical lead, currently working at Omilia as an LLM / NLU Tech Lead. My work focuses on Large Language Models, natural language understanding, reasoning, dialogue systems, and the development of robust AI solutions for conversational applications.
Previously, I co-founded Lua Health, a University of Galway spin-out focused on the early detection of mental health and wellbeing signals from language. As Chief Scientific Officer, I worked on applying NLP, psycholinguistics, and machine learning to identify signs of stress, anxiety, and depression and support earlier intervention.
Before Lua Health, I was a Research Fellow at the Data Science Institute at the University of Galway and a member of the Unit for Natural Language Processing. My research included neural machine translation, terminology integration, knowledge graphs, dialogue systems, and natural language generation.
Areas of expertise:
- LLM / NLU systems for conversational AI
- Dialogue management and reasoning
- Evaluation and robustness of AI applications
- Knowledge-enhanced NLP
- Machine translation and terminology
