Research Unit FOR5621 held its 2026 Summer School from August 20 to 21 in Grainau, bringing together students and early-career researchers from diverse academic institutions and scientific backgrounds. The two-day meeting centered on detailed presentations and open discussions, giving participants a platform to share ongoing work, debate technical approaches, and map out upcoming steps within the research unit's broader project framework.

Beyond the formal sessions, the program emphasized informal exchanges across disciplines through structured group activities. Attendees joined for a hike to the nearby Eibsee and a dedicated bouldering session. These outings provided an unconstrained setting for participants to connect, exchange perspectives across different fields, and strengthen working relationships within the FOR5621 network.
