Online materials are available for most lectures and seminars I have taught in recent years, including all material shown in the lectures plus (in some cases) supplemental materials. Both, an online version as well as PDF-files for easy downloading are available. In general, these materials are in English, even if the modules were taught while I was still at the University of Tübingen in Germany. In addition, the viewgraphs of some selected talks I have given are available as well.
If you are interested in obtaining the TeX source code of the viewgraphs for use in your own teaching, please send me an email.
