Projects

I help with the developement of Sage and I have my own sage server. If you want an account and I know you, then ask!
I also keep a list of mathematical problems to wich I don't know the solution. If you can answer one of these you would make me very happy. Note that some (but probably not all) of these are open problems.

Teaching (as assistant)

Algebra 2 (fall 2013)
Algebraic Geometry (spring 2012)
LAPP-Top, a special course for talented high school students (spring 2012)
