Biography

I am a Professor of Discrete Mathematics and Theoretical Computer Science. 

Teaching

I teach two course in Logic, basic course  and advanced level course. I also teach Analysis I for (the first year) students of mathematics. 

Research

My main field of research is in the field of Computability, more precisely on undecidable problems in automata and formal langauges and in the semigroups generated by integer matrices. Recently, I have also focused on the Foundations of Computation and related issues in the Foundations of Mathematics -- in Logic and Set Theory. I have also published articles in Combinatorics on Words.
