My general research interest is modelling and analysis of information systems (IS) in an enterprise context. I study how models can be used to facilitate broad involvement in IS development and enterprise change projects, by including other stakeholder groups in addition to ICT experts and managers. A particular interest is how models can be used for identifying and analysing safety and security threats as part of requirements work. I have also investigated how organisations actually use IS models in practice.

Recently, I have moved more and more into semantic technologies and big data sources, in particular the ones generated by social media. Current and recent projects in this area include:

  • NewsAngler - discovering unexpected connections in the news
  • BDEM - big data for emergency management
  • UbiMob - ubiquitous data for mobility in smart cities

A related research interest is 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 mostly give courses in semantic technologies, information systems, systems development, research methods and basic information technology. In these areas, I have supervised 6 Ph.D. candidates and around 50 Master students through to completion since 1990.

You can find even more of my publications in Google Scholar and at Research Gate (which also has full text available for many of them).

M.Eng. from the Norwegian Institute of Techology (1988), Ph.D. from the same place in 1992, both in computer science/computer technology.

Areas of competence: Information systems (IS), IS research methods, enterprise modelling, process modelling, IS modelling, IS development, semantic technologies, semantic interoperability, web 3.0, ontologies, software development, requirements determination, security requirements, IS architecture, enterprise information architecture, data warehouses, social information systems, social web, web 2.0.

More information is available on my LinkedIn page.

My ongoing and most recent research projects are:

  • Safety and security requirements: I participated in the NFR-funded ReqSec project (2008-2011), a collaboration with the Norwegian University of Science and Technology (NTNU). For details, see the Misuse Case Wiki.
  • Unified Enterprise Modelling Language (UEML): I am involved in the development of a unified modelling language for enterprises and their information systems. This work started as part of the EU Network of Excellence Interop (2003-2007). For details on UEML, see the uemlwiki.
  • Mobile information systems for knowledge workers: I am involved in the NFR-funded Model-Driven Multi-Channel Mobile Work (M3W) project (2006-2010), also a collaboration with the Norwegian University of Science and Technology (NTNU).
  • Process-modelling practice in Norway (PMP): I have been collaborating with the Norwegian School of Economics and Business Administration and Agder University on studies of practical process modelling in Norway.

Other research interests are:

  • Semantic modelling (recent and ongoing)
  • Ontological analysis and evaluation of enterprise and IS modelling languages (since 1998)
  • Understanding IS and enterprise architecture (since 1994)

In the past, I have also carried out research on software performance evaluation (on which I did my Ph D) and several other areas.
