If you are interested in writing a thesis (e.g. a bachelor or master thesis) under my supervision, please don't hesitate to contact me, preferably via email. The topics can be balanced with your individual interests, and are based either on recent courses or on my research interests.


It is useful if you have attended classes or seminars in my research areas, e.g. abstract algebra, topology, differential geometry, functional analysis, or operator algebras. If you are enscribed in the Bachelor programme "Mathematics", I recommend minoring in "Theoretical Physics".
