PhD studies

Lithuanian Energy Institute in cooperation with Lithuanian universities implements joint doctoral studies in the following science fields:

  • Power and Thermal Engineering (Technological Sciences) – in cooperation with Kaunas University of Technology;
  • Environmental Engineering (Technological Sciences) – in cooperation with Kaunas University of Technology and Vytautas Magnus University;
  • Economics (Social Sciences) – in cooperation with Kaunas University of Technology and Klaipėda University.


Who can apply for PhD studies:

Individuals with Master’s qualification degree or having graduated from one-level higher education system.


A PhD programme corresponds to 4 years studies (full-time mode) and consists of:

  • Independent research under supervision;
  • Courses for PhD students ( approx. 4 modules, 30 ECTS credits);
  • Writing and publishing at least 2 scientific articles;
  • Participating in at least 2 international conferences;
  • The completion of a PhD thesis.


A doctoral degree is awarded by Kaunas university of Technology to a person who has successfully completed doctoral studies and defended a doctoral dissertation.
