The NWO Gravitation funding enabled Delta ITP to fund a significant number of PhD and postdoc positions, assigned to those research projects that best served the general synergetic objectives of the Delta ITP initiative. These projects strengthened the cohesion, and involved scientists from at least two of the three institutes. With the NWO Gravitation funding ending in August 2023, the last postdoc projects were awarded in 2019 and ended in 2022.
