Bauer leaves Nestlé after 23 years with the company.
He joined the firm in 1990 as head of its Research Centre in Lausanne, Switzerland. He then held a number of management and research and development (R&D) roles, becoming executive vice president and chief technology officer in 2007.
Paul Bulcke, ceo of Nestlé, said: "Werner Bauer shaped Nestlé's R&D capabilities for more than 20 years and laid the scientific foundations for our innovation-driven approach to nutrition, health and wellness. He created a global R&D network and was also instrumental in paving the way for our future activities in the area of health science.”
He will be succeeded by Stefan Catsicas, who will take up the role on September 1.
Catsicas is currently provost and executive vice president of the King Abdullah University of Science and Technology in Saudi Arabia.
“Bringing together his extensive experience in academia, open innovation and business Stefan Catsicas has the right competences to reinforce and advance our unmatched R&D capabilities and bring them to new levels of achievement," said Bulcke.
