## Professional history

 Jul 2015 - Sep 2015 assistant professor, Department of Computer Science, FPV UMB, Banská Bystrica Jan 2015 - Jun 2015 visiting professor (at the position of assistant professor), University of Primorska, Koper 2005 - Sep 2015 research worker, SRI of Matej Bel University in Banská Bystrica 2004 - 2005 assistant, Department of Mathematics, Faculty of Natural Sciences of Matej Bel University in Banská Bystrica 2001 - 2004 PhD student, Mathematical Institute of Slovak Academy of Sciences in Banská Bystrica 1996 - 2003 research worker, Public Observatory in Banská Bystrica

## Research (more)

I am active in the fields of group actions on graphs and surfaces, maps, computational group theory and low-dimensional topology. In every field, I try to find, study and implement as effective algorithms as possible to solve (or partially solve) the problems. I use C, C++, GAP and Python as languages of implementation of algorithms

## Teaching (more in slovak)

Since 2001 I led the folowing seminars (and/or) lectures on Department of Mathematics on Faculty of Natural Sciences, Matej Bel University:
• basic usage of computers,
• elementary statistics,
• linear programming,
• discrete mathematics and graph theory,
• algebraic structures.
...and some others.
