Girls'Day 2024

APR 2024



For the nationwide Girls'Day on April 25, Fraunhofer Heinrich-Hertz-Institute (HHI) invites interested schoolgirls to explore the everyday working life of our researchers. This career orientation project aims to promote interest in STEM subjects and the associated occupational fields at an early age.

In eight different workshops, the young women gain insights into the work of each department at Fraunhofer HHI.

During the following lunch, the girls have the opportunity to ask selected female scientists questions about their work and research at the institute.

This event will be conducted in German.
