Dr. Brian O’Halloran

Brian is a highly experienced data scientist and leader that has worked across multiple sectors in his career in Ireland and the UK, including manufacturing, telecoms, insurance and newspapers. He is currently Data Science Team at Three Ireland, having previously worked in leadership roles for at companies such as Irish Manufacturing Research, Liberty Insurance and Telegraph Media Group.

Brian is currently working on developing data science and optimisation techniques/probabilistic approaches to production data, with a view to delivering production ready solutions via machine learning operations (ML Ops) frameworks.

His work at GoSmarter brings together two of the most important challenges in manufacturing data science: making probabilistic models that work reliably on messy production data, and deploying them in ways that engineers and production managers can actually use. He applies rigorous statistical techniques to problems that have historically been solved with spreadsheets and gut feel — and the results are measurably better decisions.

Brian is a recognised expert in data science leadership across Ireland and the UK. He has built and led data science teams in regulated industries where accuracy and explainability are non-negotiable, including insurance and media. That discipline carries directly into manufacturing, where the cost of a wrong prediction can be a scrapped batch, a failed audit, or a compliance breach.

He holds a doctorate and brings an academic rigour to applied data science that is rare in industry. His research interests include ML Ops frameworks, probabilistic approaches to production scheduling, and the integration of operational data with quality management systems.
