Als Abschluss der Mathe-Adventskalender 2024 fand die große festliche Preisverleihung mit fast 700 Gewinner*innen am 24.1.2025 an der Freien Universität Berlin im Audimax statt. Nach dem Mathe-Bazar wurden die stolzen kleinen und großen Mathefans aus Deutschland und dem Ausland auf der Bühne gefeiert und mit Musikeinlagen und einer Zaubershow belohnt.

A novel mathematical model, developed under the leadership of researchers from the Robert Koch Institute (RKI) and MATH+, estimates how many individuals in a given region are susceptible to different SARS-CoV-2 variants at a specific time. The model has been published in the journal "Nature".

MATH+ and the BMS are delighted to announce the arrival of two new Dirichlet Postdoctoral Fellows who have recently joined the MATH+/BMS community in Berlin. We warmly welcome Lucía Martín Merchán and Martin Winter and wish them the very best for their two-year postdoctoral positions at TU Berlin and HU Berlin.

We are delighted to announce that Laura Ciobanu Radomirovic has taken up her position as the new MATH+ Professor representing the subject area "Applied Algebra" at the Institute of Mathematics, Technische Universität Berlin as of January 2025. Congratulations and welcome to the MATH+ community.

Helena Kremp, an alumna of the Berlin Mathematical School (BMS) and a 2023 doctoral graduate of Freie Universität Berlin, was recognized with the prestigious “Ernst Reuter Prize” for her exceptional dissertation during the university’s founding day celebration on 4 December 2024.
