Locher will act as the link between product, research and corporate PR.
The qualified biologist and journalist previously handled life science topics for Frankfurt-based full-service PR agency Citigate Demuth, which is part of Incepta's Citigate PR stable.
She reports to Aventis Pharma Deutschland head of comms Kerstin von Aretin.
Aretin began a drive to better integrate communications throughout the company a year ago. The appointment of Locher should add impetus to that push.
Aretin said on the initiative: 'We want to develop corporate communications in future more strongly into business communications.
'This makes it sensible to combine the activities on an organisational level, too.'
