Idea Forum for younger researchers

Idea Forum for Younger Researchers


We encourage to take part in the self-organized Idea Forum for the younger researchers. Here  ideas, research challenges, work processes, problem solving or other are shared, stimulating collaboration across both the theoretical and experimental field, as well as between Ph.Ds, Post Docs, researchers and master students.

Journal Club

Upcoming Journal Clubs


The journal club is arranged bi-weekly on Fridays from 1.15 -2.15 PM.

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.
