As a young doctor of mathematics working at the Mathematical Institute of the Academy of Sciences in Prague, I offer lessons to all class levels. During my PhD studies at the University of Paris (2014-2017), I was a private tutor to undergraduate students. Before enrolling to PhD studies, I was a teaching assistant at the University of Novi Sad for two years. My experience is, therefore, twofold. But, what is most important, my students love me!
