The Geo.X Career Development Program is optimized for the specific requirements of Young Scientists. It aims to enhance competences in science and professional skills. Consequently the program extends the view of career possibilities inside and outside academia, for example by our annually organized Career Days. Numerous activities are embedded in the frameworks of the whole Geo.X network and take place with the Geo.X Early Career Scientist Section. Scientific evidence on obstacles and challenges for career development of early career scientists in the Geo.X research network is studied by an Accompanying Research.
