Machine learning: Development of novel cluster analysis and dimensionality reduction algorithms, with a particular focus on their application in text mining tasks.

Network analysis: Development and application of clustering and community finding algorithms to dynamic social networks.

Social media analytics: Using data mining and visualisation to explore trends and behaviours in online social media platforms. This has included work on topic modelling, sentiment analysis, content curation, and user recommendation systems.

Digital humanities: Application of network analysis and text mining techniques to explore patterns in literary fiction, in collaboration with the UCD School of English.
