I am currently a senior developer at mCASH Norge AS.
I am on leave from a PhD scolarship at the Institute of Theoretical
Astrophysics at the University of Oslo. I will return 30% sometime 2014 to finish up,
the foundation of my thesis is laid in the most recent paper below.
My research focus on new computational algorithms to accurately analyse the
Microwave Background, by using methods from numerical
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 Hashdist projects.

- (This list is a bit out of date.)
- I'm one of the developers of
("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.
