I'm a mathematician working at University of Bonn. As a standard, I use (AMS-)LaTeX and BibTeX for my documents.
My main research interest is variational calculus, in particular a generalized notion of gradient flow.
I have also been involved in a few programming projects, using Delphi 2007, MySQL and PHP. I mainly work on datastructure and algorithms (the stuff going on 'behind the interface').
