After completing the master’s program, it is possible to apply for doctoral studies. Doctoral studies are a special form of study, where the main emphasis is on the individual development of the doctoral student as a future researcher or top specialist of the company. Therefore, the volume of auditory study is smaller, and the share of individual research is higher. The early-stage researcher works as a full-fledged member of the research team and contributes to the achievement of the laboratory’s research and development goals. Doctoral dissertations can be carried out in cooperation with companies contributing to innovation. A particular form of doctoral study, industrial doctoral student, has been created for this purpose.
