- IoT analytics
- Linked Data and Semantic Web technologies
His current research involves optimisation for keyword earch and distributed queries in decentralised data infrastructures, such as environemnts with personal online datastores where individuals maintain control over access and processing of their data. He is also interested in sociotechnical approaches to the identification and elimination of bias in datasets and inaccessible algorithms making use of crowdsourcing approaches, and in federated learning in decentralised infrastructures for the identification of cybersecurity threats.
