Christian O' Leary

Senior Researcher

Christian O’Leary is a senior researcher in Artificial Intelligence (AI) at the Nimbus Research Centre with interests in Machine Learning, Optimisation and Multi-Agent Systems. Working within Nimbus’ software team, he has worked on applications involving Computer Vision, Forecasting, Anomaly Detection, Chatbots, Sentiment Analysis and Schedule Optimisation. He has been a Principal Investigator managing some of Nimbus’ Cyber-Security projects and also has experience as a full stack developer working with a range of domains including smart microcontrollers, cloud deployments (AWS, GCP, Azure), desktop applications and web applications.

He has completed a MSc in Artificial Intelligence from CIT (2020) with a thesis on using Capsule Networks for Day-Ahead Electricity Price Forecasting. He also completed a BSc in Computer Science at UCC (2017) with a project on Multi-Agent Communication in a Search Situation. He has previously worked in Johnson Controls (formerly Tyco) as a Software Engineer.

His research interests include: AI, Machine Learning, Deep Learning, Reinforcement Learning, Metaheuristics, Decision Analytics, Image Processing, Time Series Modelling, NLP, Multi-Agent Systems, Software Architecture and Design
