On 19 December 2025, Julian Johannes Mittmann-Götsch successfully defended his doctoral thesis on ‘Plants, microbes and soil redox in salt marshes: Intricate interactions and responses to global warming’. To mark this special occasion, his research group, other members of RTG 2530, and numerous friends and family members gathered at the Institute of Plant Sciences and Microbiology (IPM) at the University of Hamburg to support Julian and celebrate with him.

In a decorated seminar room at the IPM, Julian presents the creatively designed doctoral hat to his guests under colourful garlands. In addition to many personal dedications, it features an impressive miniature version of the ‘Marsh Ecosystem Response to Increased Temperatures (MERIT)’ experiment, which is set up in the salt marshes of the Wadden Sea on the North Sea coast. This is where he conducted a significant part of his research. Photo: UHH/RTG2530/Grebe
