Mathias Wiedemann will take over as president of WACKER BIOSOLUTIONS on January 1, 2025. He succeeds Susanne Leonhartsberger, who will leave the company at her own request at the end of 2024.

“I am delighted that we have been able to recruit Mathias Wiedemann, an outstanding colleague from our own midst, to head our biotech division. I wish him every success in his new role,” says WACKER CEO Christian Hartel. Wiedemann previously headed WACKER’s POLYMERS business in the USA. His new assignment sees him returning to Munich. “BIOSOLUTIONS offers exciting products and services. I look forward to meeting this challenge. We are pursuing ambitious growth targets with a great team. Our goal is to generate one billion euros in sales in 2030,” explains Wiedemann.

Mathias Wiedemann studied engineering and business administration at the University of Bremen, where he earned his doctorate in engineering on a scholarship from WACKER BIOSOLUTIONS. He joined WACKER as a project engineer in 2011. After holding several specialist and managerial positions in Germany and abroad, he was most recently responsible for POLYMERS’ business in North and Central America. In May 2024, Wiedemann was also appointed CFO of Wacker Chemical Corporation.

Susanne Leonhartsberger took charge of the BIOSOLUTIONS division in 2020. She joined WACKER in 2001 and has been instrumental in developing BIOSOLUTIONS in various functions both in Germany and elsewhere. Development milestones under her leadership include the establishment of an mRNA competence center in Halle/Saale, Germany, in the context of the pandemic-preparedness agreements with the German government. “Susanne Leonhartsberger has taken BIOSOLUTIONS a decisive step forward on its growth path,” emphasizes Hartel. “On behalf of the entire Executive Board, I would like to thank her for her commitment and dedication. We wish her all the best for the future.”
