Profile
As the science officer I assist the institute’s management in day-to-day operations as well as in the strategic development of IGB.
My tasks include
- coordination of internal processes, e.g. with regard to quality management (reporting, audit, evaluation) and support of organisational and personnel development measures,
- support of internal communication and networking within IGB through events and internal funding schemes,
- representation of IGB in various working groups and committees; mainly matters concerning the Leibniz Association, the Forschungsverbundes Berlin e.V. and the Scientific Advisory Board.
