Forskning

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.

Undervisning

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.

Prosjekter

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.
