This year, we will have three invited speakers! One internal and two external. They have been chosen by popular vote. We're looking forward to their talks!

Prof. Dr. Klaus Altmann

Freie Universität Berlin

Klaus Altmann was a Professor of Algebraic Geometry at Freie Universitaet Berlin from 2002 - 2025. After completing his PhD at Humboldt-Universitaet zu Berlin, he received a Heisenberg grant and had been at the universities of Jena, Kaiserslautern, and M.I.T. (USA). His first tenure position was in Duesseldorf. The research interests of Altmann are the usage of discrete mathematics within algebraic geometry. The most striking key word for this is that of toric varieties.

Prof. Dr. Marie-Charlotte Brandenburg

Ruhr-Universität Bochum

Marie-Charlotte Brandenburg is a Junior Professor for combinatorics at Ruhr-Universität Bochum. She studied mathematics at Freie Universität Berlin and completed her PhD at the Max Planck Institute in Leipzig in 2023. After postdoctoral positions in Leipzig and Stockholm, she moved to Bochum in 2025. Her research focuses on polyhedral structures, inspired by questions from tropical geometry, optimization, and the geometry of neural networks.

Dr. Benedikt Gräßle

University of Zürich

Benedikt Gräßle is a postdoctoral researcher in numerical analysis at Universität Zürich. He studied Mathematics and Computer Science at Humboldt-Universität zu Berlin and was a student of the Berlin Mathematical School, completing his PhD in 2024 on the a posteriori error control for finite element methods. His research focuses on reliable and efficient numerical methods for PDE, including rigorous error estimation, certified eigenvalue computations, adaptive discretisations, fast solvers, and boundary integral methods for scattering problems.
