Dag Sjøberg received his MSc degree from the University of Oslo in 1987 and his PhD degree from the University of Glasgow in 1993,
both in computer science. Since 1999, he has been Professor in Software Engineering at the University of Oslo. Previously, he worked as a
statistician and computer scientist at the National Hospital of Norway, as a software developer and group leader at Statistics Norway,
and was an Associate Professor at the University of Oslo. He has been on the board of three software development companies.
In 2001, he founded the Software Engineering Department at Simula Research Laboratory and was its leader until 2008, when it was number 1
in the world (out of 1400 institutions) with respect to publications, on the basis of a
ranking by the Journal of Systems and Software (JSS)
for the period 2004-2008. He was number 11 (out of 4000) on the ranking of individual scholars for the period 2003-2007. He was also
Research Director and part of the Simula management team.
He has been the leader of many externally funded research projects. Since 1996, he has, together with SINTEF and the Norwegian University
of Science and Technology (NTNU), continuously run projects for the improvement of software development processes and for innovation in Norwegian industry, including
such organizations as ABB, Telenor and DNV Software, and many others.
Among his research contributions are the insights gained from a significant increase in the realism, scale, and control of empirical studies
in software engineering. By attracting appropriate funding, setting up professional project organizations, and developing web-based support
environments, he has initiated and organized a large number of experiments with subjects ranging from 300 professionals from 30 companies
for 1 day to eight professionals for 2 months. To further understand the complexity of software engineering and the costs/benefits of
using various software engineering technologies (processes, methods, and tools) for various purposes by people with varying skills in various
industrial contexts, he has engaged in how software engineering research may benefit from applying other empirical methods as well, including
case studies (possibly controlled, comparative, multiple, and/or longitudinal), action research, surveys, systematic reviews of the literature, and
meta-analyses. He has also been active in the issue of theory building in software engineering.
He was on the Editorial Board of Empirical Software Engineering from 2002 to 2009. Since 2010, he has been on the Editorial Board (Associate Editor) of
IEEE Transactions on Software Engineering (Impact Factor 3.75).
