By winning a grant for a junior research group, their leaders demonstrate their high potential for a scientific career. Leading a junior research group offers a special opportunity to develop scientific independence at an early stage, to develop one’s own scientific profile and to gain competence and experience in leadership. Therefore, ZALF offers start-up grants to support the proposal writing for a junior research group for promising early career researchers. The development of competencies for group leadership, supervision or teaching is also supported. At ZALF, independent junior research groups can in principle be located within working groups or be established directly as a ZALF separate working group - depending on the individual case and agreements.
