I am a professional mathematician at the Faculty of Mathematics, University of Vienna (Austria), where I have been engaged both in teaching and research (mainly discrete geometry).

I have a broad interest in (almost) all subjects of mathematics, mathematical logic, computer science, history of mathematics (and science), (and applications of mathematics).

Equally, I am also interested in many aspects of human culture.
