I was born in Lviv. Graduated from Lviv secondary school with a golden medal. Then received higher education in the field of “Applied Mathematics”, received a diploma with honors and got the qualification “engineer-mathematician”.

I have worked for 4 years in engineering positions at the Research Radio Engineering Institute. I was engaged in the development of software for real-time systems and system programming of specialized computing machines.

After moving to teaching, I constantly work at the Ivan Franko National University of Lviv. Studied at the postgraduate study at the Institute of Cybernetics at the Academy of Sciences of Ukraine (Kiev), where I have  prepared and defended PhD dissertation on the topic “Semantic debugging of programs by the method of finding fixed errors”, obtained a scientific degree of the candidate of physical and mathematical sciences.

Associate Professor of the Department of Programming. The total amount of publications is about 100.

Besides of work at the department I have worked as a teacher of computer science at the Lviv Physics and Mathematics Lyceum for 10 years, have prepared a number of prizewinners of programming competitions among the students.

Sphere of scientific and practical interests – theory and practice of programming, system software of computers, algorithms on graphs, methods of teaching programming.
