Description of the Study Program

The PhD program in Informatics is designed to attract students who want to solve computer science problems that have no satisfactory solution yet, or that have not yet been formulated at all. For the students it is an opportunity to find an area of informatics that is most appealing to them, focus on a specific problem, and devote their energy and efforts during the years of their studies to the solution of the problem. The direction of the research is coordinated with a supervisor, whose main role is to guide and support the student in his/her research. In cooperation with the respective department, the supervisor aims to provide best research conditions for the student.

Currently, this PhD program is focused mainly on the following areas: theoretical computer science, security of information systems, artificial intelligence, computer graphics, bioinformatics, and cognitive science.

Prospective students should apply for particular theses topics. Oftentimes, supervisors adjust the direction of the topic to suite the interests of the candidate. An early contact with a potential supervisor is an important step towards choosing a mutually interesting topic, and subsequently, toward a successful completion of the studies.

Doctoral Scholarships

Full-time doctoral students who have permanent residency in the European Union are entitled to receive a scholarship for the entire standard duration of their studies. The scholarships are paid starting on the date of enrollment. The scholarship is determined in accordance with the tables included in the Law no. 553/2003 Z.z. as follows: 

  • prior to completion of the qualification exam: 807,50 EUR (6th class, 1st level)
  • after successful completion of the qualification exam: 940,50 EUR (7th class, 1st level)

Scholarships are not subject to taxes or other fees.

Doctoral studies are considered an equivalent to full time employment and in the majority of cases cannot be combined with another employment. Job holding applicants who intend to keep their job are advised to apply for the external (distance) form of doctoral studies. Doctoral students enrolled in the regular form are expected to participate in teaching activities such as conducting recitations or exam grading, in accordance with the needs of their corresponding departments.
