Research interests

My research focuses upon the dynamic relationship between development and use of ICTs in organizations, with particular emphasis on the interplay between the technical and the non-technical. I am currently pursuing this topic by studying how organizations use ICTs for handling risks in practice. Specifically, I do so in two different projects:

• ICT use for safe and reliable operations in oil and gas production
• The societal implications of using ICTs for risk management in airport security

I have previously explored the relationship between development and use of ICTs by studying maintenance of an integrated system in an open source community of volunteers.
