- Mathematical Analysis - Integral theory
- University Math didactics and teaching - how to teach better. I also co-organize seminar (czech only) Talking on teaching.

I like Open source software. My operation system is the one with the penguin, especially Ubuntu distribution.

All materials arise in
Vim,
then are typeset by
L^{a}T_{e}X.
My favourite graphic editor is Gimp,
Graphs of functions are sketched in
KmPlot,
Geogebra
and in Mathematica.

Fractals, like the above one, are generated by Fraqtive.

I do historical fencing, play the guitar. In summer I go hiking, on the weekends I do puzzlehunt: Sendvič, Bedna a Tmou.
