My current research interests are knowledge graphs, ontologies and related AI techniques such as large language models. Several of my ongoing and recent projects investigate how these and other AI techniques can be used the media sector, often in combination with big open data sources.

My current research builds on a long-standing interest in modelling and analysis of information systems (IS) in an enterprise and usage context. I have studied how various types of conceptual models can be used to facilitate broad organisational involvement in IS development and enterprise change projects, by including other stakeholder groups in addition to ICT experts and managers.

I have investigated how models can be used for identifying and analysing safety and security threats as part of requirements work and how organisations actually use IS models in practice.

I have also investigated the semantics of IS and enterprise modelling notations. I am studying how clearer definitions of notation semantics can contribute to making better models and to facilitate consistency checking and perhaps even automatic translation across different notations. My work on a Unified Enterprise Modelling Ontology (UEMO) is part of this activity.

     

    I give courses in areas such as knowledge graphs, big data, information systems, systems development, research methods, Python programming and basic information technology. In these areas, I have supervised 9 Ph.D. candidates and more than 50 Master students through to completion.
