EOES 2025
Dear Participants of EOES 2025,
As the Dean of the Faculty of Science at the University of Zagreb, it is my great honor to welcome you to our Faculty as we host the European Olympiad of Experimental Science (EOES).
I am delighted to extend a warm welcome to all participants, mentors, and students from across the European Union to our capital, Zagreb, and to Croatia.
Having such talented young scientists, who have already excelled in their respective countries, in our laboratories is a privilege for us. The Olympics have long represented the pinnacle of achievement, dating back to ancient Greece, inspiring individuals to strive for excellence. The adaptation of this competitive spirit to the realm of science has proven to be incredibly effective, as evidenced by numerous Science Olympiads around the globe. We are grateful for the opportunity to be part of this exceptional scientific network by organizing EOES 2025.
Science is a domain where discovery knows no bounds, and we believe that the experiences you will encounter here at our Faculty will not only broaden your knowledge but also inspire further scientific achievements.
In addition to the competition, our organizing team has planned memorable socio-cultural activities to enrich your experience.
We warmly welcome you to this exceptional event and look forward to seeing you in the spring in Croatia.
Best regards,
Mirko Planinić,
Dean, Faculty of Science
University of Zagreb
