to my homepage. I am a mathematician at Aalborg University, Department of Mathematical Sciences. My research these days is in the new field: Geometry and Topology with applications in Computer Science. I made a poster presenting our work. My first ever Beamer poster...
If you want to know more about me, you may check my publications. via the Aalborg University listing. Notice that this list contains everything from newspaper articles to scientific publications.


I have been the main author of the Danish blog Numb3rs. The blog is in Danish and I try to explain the maths in the TV-series Numb3rs.

Matematik 5
Mapprojections (in Danish, but with links to pages in English)
Foredrag for gymnasie-, htx-,hhx- og andre klasser

A newspaper article which I wrote for the World Math Year. (in Danish). At some points, pi has become p, but it is not hard to see where.
I have been interviewed to the internetmagazine Forum For Gender and Culture. The interview is in Danish and can be found here.

For some really interesting and well written articles about mathematics written by Keith Devlin check Devlins Angle. The newest columns are here.
Harvey Mudd College has a list of Fun Facts about mathematics. Some of them are more fun than others, but see for yourself.
The American Mathematical Societies have a Mathematical Awareness Month.
Pi. A movie which is a bit to advanced for my taste (not on the math part, but as a movie...). It did, however, get very nice reviews and won a price at the Sundance festival. So if your taste in movies is not as primitive as mine, maybe you will love it...
