This summer I had the chance to attend the ITER Summer School 2025,
which was focused on Integrated modelling. For me, as I am early in my career,
it was not only about learning new things but also about meeting people, and
acquiring a broad view of the topics in nuclear fusion. 

The lectures were very rich, covering everything from the wall until the core.
At times it was a lot to take in, but I enjoyed seeing how different parts of fusion
research link together. One thing that I got out of most of the lectures is that
it is not enough to consider just one regime or component of a system, but it is
necessary to do the modelling in an integrated manner and that collaboration
is key for accurate predictions. That perspective was really valuable for me.
One of the highlights for me was the visit to the ITER construction site.
I had seen photos before, but being there in person was completely different.
The scale of the machine was overwhelming, and it made me realize how much
effort and coordination from people all over the world goes into this project.
Particularly it was impressive how precise the assembly needs to be compared
with respect to the size of the vessel parts. 

Another important part of the experience was meeting the other participants.
The group was very international, and I really enjoyed hearing about other
people’s research and career paths. Some of the best moments actually happened
outside the lecture room, during coffee breaks or dinners, when conversations
flowed more freely. I did not have the chance to present a poster, but one of my
favourite parts of the event was the poster sessions in which I could hear about
other people’s research in their own words. 

Overall, the ITER Summer School was a very rewarding experience for me.
I learned a lot of new things, but more importantly, I left with new motivation
and a clearer sense of direction for my own work. Also, I have made many
connections around the globe, which may turn into long-lasting friendships and
or lead to future collaborations.
