During this year's seminar week, the 22 participants from the working group travelled to Hirschegg in Austria's Kleinwalsertal and presented at the Darmstädter Haus the status and progress of their current research. The presentations were always followed by dynamic discussions on the individual research topics. Following the technical program, the working group was offered an ideal setting for joint group activities. Among other things, the group hiked around the Widderstein in sunny weather accompanied by a mountain panorama view.
