Teaching

I teach courses in engineering (statistics, calculus, linear algebra) as well as in mathematics and computer science programs (discrete mathematics, algebra, logic). Occasionally, I conduct more advanced classes for interested students (modal logic, dynamic logic, model theory, set theory, combinatorial algebra, algebraic number theory).

Most of the materials for students are available on the LEON platform.
