Education

  • 1994 Comenius University in Bratislava, Slovakia -- master degree in computer science
  • 2001 Slovak University of Technology in Bratislava, Slovakia -- PhD in applied mathematics. Thesis title: Quotients of partial abelian monoids

Employment

  • programmer for MicroStep HDO, meteorological software 1994--1998.

  • Slovak University of Technology, assistant (later associated) professor 1998--now.

Teaching

  • Basic courses in math (algebra, discrete mathematics, caclulus), most of the time.
  • Since 2008: Operating Systems, Computer Networks, Internet Applications.

Research

I work in

  • quantum logics: effect algebras, orthomodular lattices,
  • MV-algebras,
  • finite posets.

I try to learn something about

  • algebraic topology,
  • algebraic combinatorics.
  • category theory
