Office Hours: By appointment


  • Ph.D., Roland Eötvös University, Budapest (Hungary), Ergodic Theory and Dynamical Systems

I regularly teach the Algebra I, Linear Algebra, and Ergodic Theory graduate courses with great enthusiasm and pleasure. My primary goal in those courses is to teach the students the way of modern mathematical thinking, especially the abstract way algebraists conceive the mathematical world. For this purpose I have developed my own brand new curriculum for the abstract algebra and ergodic theory courses that I distribute, along with my notes and homework problems, to students electronically. I regularly present enlightening examples related to my own research  to my students, and in this way integrate my research into their education. Ten years ago I served as the department's Graduate Program Director, which gave me a very good opportunity to learn more about the needs of our graduate students: Where, and in what respect, we should improve our graduate program, curricula, etc.

I am a member of the Editorial Board of the journal Ergodic Theory and Dynamical Systems.

Research Interests

Ergodic theory and dynamical systems with particular emphasis on systems with algebraic flavor.
