Pure studies are simply too theoretical for many people. This is also how Marie felt. Back when she chose her bachelor course, she opted for a dual study programme for applied mathematics and computer science at the Aachen University of Applied Sciences, which included vocational training as a technical software developer at Forschungszentrum Jülich. But it didn’t stop there: she liked the combination of theory and practice so much that she started a position as software developer at the Institute of Energy and Climate Research in addition to her master’s studies. There she is busy gathering data for her current project and investigating how energy management can be made as efficient as possible on the campus of the research centre.
