Bachelor- and Master Theses

Lots to do ... Just have a look at our publications and pay us a visit for a little chat.


For a brief summary of our publications look here (since 2002)

A more extended list is part of my CV.

I have a rather extensive Bibtex file that you might wish to use (together with one auxiliary file). I could offer help getting a copy of any of the cited papers.
