JSI OPEN DAY 2026
Open Day at Jožef Stefan Institute is intended for the general public – anyone who wants to find out what we are researching at our institute and how this can contribute to a balanced society of the future.
The first programme section of the Open Day will start at 9am (CET) at the Jožef Stefan Institute (Jamova cesta 39). Each programme section starts at the full hour and lasts 1 hour. At 10am, 11am and 12pm, the guidance will also be in English. The last presentation will start at 1pm.
Parking will not be available at the Jožef Stefan Institute (Jamova cesta 39), but visitors will have an option to park at the parking place near the Faculty of Mathematics and Physics (Jadranska ulica 15). The number of these parking places is limited.
Visits will also take place at the Reactor center Podgorica in a close vicinity of Ljubljana (Brinje 40, 1262 Dol pri Ljubljani) in the scope of programme section 4.
