I am a doctoral student in the Institute of Theoretical Astrophysics at the University of Oslo. I work with analysing the Cosmic Microwave Background, by using methods from numerical statistics (Gibbs sampling). My supervisor is Hans Kristian Eriksen.

I also have a strong interest in scientific Python for High Performance Computing. I'm involved in the Cython and Fwrap projects.

• Cython tutorial; Behnel, S., Bradshaw, R. W. and Seljebotn, D. S.; Proceedings of the 8th Python in Science conference (SciPy 2009)

• I'm one of the developers of Cython ("makes writing C extensions for the Python language as easy as Python itself"). My main contribution is features for numerical computation with Cython.
• I once started a project/wiki/mailing list about running Linux on the Compaq EVO T20.
