Passionate about creating measurable business impact while developing people into future leaders. --- In my current role as Group Digital & Excellence Officer (EVP) at Heraeus, I lead the Heraeus Excellence unit (Commercial & Supply Chain Excellence) and the Heraeus Digital Hub, guiding 65 professionals across Europe, Asia, and the US. I work closely with the Board and business unit CEOs, ensuring alignment, trust, and measurable impact at the highest level. Each year, my teams deliver over 100 projects with an average customer satisfaction of 8.9/10, spanning AI-driven solutions in manufacturing, quality, customer service, innovation, and sales. A key achievement has been transforming the function from a traditional corporate cost center into a unit with scalable, value-adding services recognized across the group. Beyond digital initiatives, my team and myself steer strategic projects such as business line strategies, Value Creation Plans and corporate startup evaluations, often working directly alongside business unit managing directors. The unit has evolved into both a trusted transformation partner and a talent flagship, with many alumni advancing into leadership positions across Heraeus. What drives me is creating sustainable value through innovation, data, and clear strategies – while developing people into leaders. Key interests: Digitalization, AI in industrial applications, change management, and leadership. Outside of work, I am actively involved in my family’s wine estate and enjoy politics and film.
