His international experience includes more than ten years living in the United States. Torsten Woehr earned his Ph.D. in bioorganic chemistry from the Swiss Federal Institute of Technology (EPFL) in Lausanne.

He brings extensive transatlantic experience as well as a proven track record in the CDMO industry—from the successful implementation of commercial strategies to drive company growth to building trusting customer relationships. At a time when our customers are facing increasing complexity in the development and manufacture of biologics, his expertise in aligning commercial priorities with operational capabilities and strengthening partnerships will be crucial. I am confident that, under his leadership, we will continue to deliver sustainable value to our customers and their patients.”

In doing so, we will continue to be guided by our vision of advancing medicine to protect lives—together.”
This appointment marks the start of the next phase of the company’s strategy, which aims to further strengthen long-term growth and sustainable value creation. Following a period of interim leadership, Uwe Buecheler will step down from his role as interim CEO effective August 1, 2026, and resume his position as Vice Chairman of the Supervisory Board.
