He will succeed Dr. Robert Reiter who has decided to retire after 27 years with the company and 34 years in the industry. In his current role, Mike Graham is leading the company’s Plant Breeding organization and has profound expertise in R&D and agriculture. The change will become effective as of April 15, 2025.

Robert (Bob) Reiter joined the company in 1998. He helped revolutionize breeding through the use of genotypic selection and led the development of an industry-leading genotyping platform. Over the years, Bob Reiter has held various senior roles in R&D helping to further shape Bayer’s industry-leading seed and trait capabilities. After serving as Head of Global Supply Chain, he became Head of R&D for the Crop Science division in 2018. Under his leadership, Bayer successfully advanced upcoming blockbuster products like the new herbicide Icafolin and the Preceon Smart Corn System which has the potential to revolutionize corn production going forward.

“Throughout his career, Bob has been a strong advocate for agricultural innovation. He has truly advanced and supported farmers' ability to produce more while saving natural resources at the same time. I want to express my sincere appreciation to Bob for his tremendous contribution and commitment to the company,” said Rodrigo Santos, Member of the Board of Bayer AG and President of the company’s Crop Science division. “I wish Bob all the best for his well-deserved retirement. He will be missed not only by the R&D organization, but by all Crop Science colleagues around the world.”

Bob Reiter will actively support his successor in taking over his new responsibilities to ensure a smooth transition. Mike Graham joined the company in 1996. From his early days as a plant breeder, he has steadily advanced his career, taking on roles with increasing responsibility.
