To assist in making the transition to/within Germany easier, HAPN has compiled a non-exhaustive list of PostDoc fellowships that can be received up to seven years after PhD conferral. The idea is that one can easily compare the funding rates, benefits, and conditions of the various fellowships to decide which fellowship suits the researcher the best, as well as receive some helpful advice from previous fellowship holders. As stated, the list is non-exhaustive and only provides a brief overview but includes the relevant links where one can ask more detailed questions. Further information on research in Germany can be found here.
