These are two six week blocks spent in the participating laboratories in order to complete a small research project. The aim of the rotations is to familiarize newly recruited candidates with the IMPRS and vice versa. Two such rotations are taken consecutively before the start of the thesis and should be done in two of the participating institutions, ideally in Kiel and in Plön. One rotation usually takes place in the lab where the PhD thesis is planned. The location for the second rotation is chosen together with the supervisor so that the interests and skills of the student are complemented. Based on two reports and one oral presentation the performance of the student will be evaluated by the IMPRS faculty.
