I manage the Information Security group.


I strongly believe in applying computer science theory to solve problems in software engineering practice.

ECOOP 2009 Best Paper (with Einar W. Høst)


I'm currently involved in the following projects:

In 2017, I took part in organising the 50 years anniversary of Simula, the first object-oriented programming language.

Summer interns

I've had some very talented students working with me as summer interns before their master degree. Typically, NR will put out a call for summer internships early spring.

Patrick Henriksen (2018, UiO): Working on authentication using machine learning on smartphone sensor data.

Edvard K. Karlsen (2011, HIST, NTNU): Working on static code analysis, resulting in a paper on the quality of the Norwegian e-voting trial.

Science and politics

Technology is not neutral, and what we choose to work on—as researchers and developers—matters.

After nearly two decades as a member, I will not be renewing my ACM membership this year. It started with the December 2015 issues of Communications where the editor was unable to argue for a ban on lethal autonomous weapons. I wrote a letter to the editor arguing that working on such weapons was inconsistent with the ACM Code of Ethics and Professional Conduct. Then in 2018 the code was revised to, among other things, include the concept of intentional harm. In my view the revised code no longer prevents working on LAWs, which I find preposterous.


You think you know when you learn, are more sure when you can write,
even more when you can teach, but certain when you can program. -- Alan J. Perlis
