I teach the courses Introduction to Differential Calculus (2 ECTS), Applications of Differential Calculus (2 ECTS), Integral Calculus (4 ECTS), Linear Algebra a (5 ECTS), and Linear Algebra b (4 ECTS).
Research interests in pure mathematics:
- mathematical analysis, and in particular, complex analysis;
- differential equations in a complex domain, growth and oscillation of solutions;
- inner functions, and in particular, Blaschke products.
