Research interests

I study the integration and exchange of data and knowledge within organisations and on the web. That is, ways to bring together, understand and process vast amounts of heterogeneous and distributed data and information, via unifying access and building data warehouses. I also work on developing frameworks for supporting data usage contracts; these are technical specifications that describe intentions and agreements of data usage, privacy policies and user consent. I am also interested in supporting the sharing of private data across Databases, Knowledge Graphs and Blockchains.

I am developing algorithms and systems to address these questions. Tools that help in this direction are database theory and technologies, the semantic web, ontologies, and distributed systems.
