Christian Bär held professorships in Freiburg and Hamburg and is now a professor of geometry at the University of Potsdam. He works in differential geometry and applications to mathematical physics. He was the president of the German Mathematical Society and, in addition to his work in research and teaching, is the editor-in-chief of zbMATH Open.Bernhard Hanke has held the Chair of Differential Geometry at the University of Augsburg since 2010. Prior to this, he was a professor at the Technical University of Munich (TUM). His research interests include differential geometry and topology, with a particular focus on scalar curvature geometry. From 2016 to 2026, he served as the coordinator of the DFG-funded Priority Programme Geometry at Infinity.Anna Wienhard is a director at the Max Planck Institute for Mathematics in the Sciences in Leipzig. Her research explores geometric structures, Lie groups and their discrete subgroups, and higher Teichmüller spaces. She has been awarded a Sloan fellowship, the Hector Science Award and several ERC grants. She is a Fellow of the American Mathematical Society, a member of the German National Academy of Sciences Leopoldina and several other academies. Burkhard Wilking was a professor at the University of Pennsylvania before moving to his current position in Münster in 2002. He works in differential geometry, in particular, on lower curvature bounds and Ricci flow. He has been awarded a Sloan fellowship, the Leibniz prize and the Staudt prize.
