The successful candidate will work in collaboration with researchers at GFZ and UCLA and other institutions in greater Berlin metropolitan area on the development of numerical codes and comparison with in-situ observations. The research will be focused on understanding of the wave-particle interactions and the dynamics of energetic particles in the near-Earth space. The candidate is expected to have demonstrated experience of working with numerical simulations and observations. Both researchers several years after PhD and more senior scientists will be considered for this position. The level of appointment will depend on experience and demonstrated ability to conduct independent research.
