MSD Germany has appointed Dr Susanne Fiedler as CEO to take over from Hanspeter Quodt, who steps after seven years in the post.
Dr Fielder first joined the German operations of Merck & Co in 1997, when she took up a role in market research.
She then moved to market, initially as a product manager and later as a marketing manager and then a business unit head with responsibility for a number of MSD products.
Since then Dr Fielder has served in the US, where MSD operates at Merck & Co, as global brand leader for the diabetes treatments Januvia and Janumet, before taking up a Sydney-based role as managing director of MSD Australia and New Zealand.
She will officially take on her new role on 1 February, when Quodt moves to a new European level position.
