Idea Forum for younger researchers
Idea Forum for Younger Researchers
We encourage to take part in the self-organized Idea Forum the younger researchers. Here projects, ideas, and research challenges are shared, stimulating collaboration across both the theoretical and experimental field, as well as between Ph.Ds, Post Docs and researchers.
Upcoming Journal Clubs
We arrange bi-weekly Journal Clubs where we focus on articles with a specific field or topic with the aim of learning the topic. The expectation is that the audience should be able to learn from the presentation alone. The discussions are mediated by a chair. All members are expected to participate.
