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.

Science

I work in

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

In addition, I try to learn something about

• algebraic topology,
• algebraic combinatorics.
