I am Professor and Head of the Department of Industrial Information and Control Systems at the Royal Institute of Technology (KTH) in Stockholm, Sweden. At the department, we do research on the analysis of architectural models of information systems in their context. Much work is directed toward the electricity sector, with a particular focus on those systems that control electric power transmission and distribution. Significant research is also aimed at enterprise-wide information systems of a more general kind. In this area, we have written a book with the title Enterprise Architecture: Models and Analyses for Information Systems Decision Making, available in many book stores. I am secretary of the IFIP Working Group 5.8 on Enterprise Interoperability, technical coordinator of the FP7 Viking project, organizer, program committee member and associate editor of several international conferences, workshops and journals (see below for current calls for papers). I am a member of the Faculty Assembly of the Royal Institute of Technology. I supervise a number of PhD students (see below for that too). In our research we have much contact with Swedish corporations and organizations in the form of research projects, master thesis projects, seminars and consultations. I received my MSc from the Lund Institute of Technology in 1997 and my PhD and Docent title from the Royal Institute of Technology in 2002 and 2007. I was appointed professor in 2009.

Many of my recent publications are available here.

I do research on enterprise architecture in general, and architecture analysis in particular. In the last decade, enterprise architecture has grown into an established approach for management of the information systems in an organization. Enterprise architecture is model-based, in the sense that formal descriptions of the systems and their environment constitute the core of the approach.

The purpose of architecture models and conducting analyses of these is to facilitate the making of rational decisions about information systems in an organization. A rational decision maker is an agent facing an alternative after a process of deliberation in which he or she answers three questions: "What is feasible?", "What is desirable?" and "What is the best alternative according to the notion of desirability, given the feasibility constraint?". Translating these questions into the context of enterprise architecture analysis, architectural scenarios answer the first question of what is feasible. Answers to the second question regarding desirables, are often expressed in terms of the change of various information system properties such as increased information security, increased interoperability, increased availability, etc. The answer to the third question, providing the link between the feasible to the desirable, i.e. the link between the scenarios and the properties of interest, is given by architectural analysis.
What constitutes a "good" architecture model has thus far not been clearly defined. This is due to the fact that the "goodness'" of the model is not an inherent property, but contingent on the purpose the model is intended to fill, i.e. what kind of analyses it will be subjected to. For instance, if one seeks to employ an architecture model for evaluation of the interoperability of an information system, the information required from the model differs radically from the case when the model is used to evaluate the system's availability. The topic of my research is to improve on architecture models and the analyses performed upon them. Currently, I focus particularly on the analysis of information security, interoperability, modifiability, and business utility.
