The purpose of doctoral studies is to train scientists who are able to independently perform research and experimental development work and solve scientific problems. The duration of full-time doctoral studies is up to 4 years, part-time - up to 6 years. Both full-time and part-time doctoral studies can be financed by the state, full-time studies are still financed from the EU structural funds, and part-time studies can be financed by the student (or the institution supporting it).
