The winter school will feature a series of short lecture courses (2-4 hours each) on the main topics of the program. These are designed to give graduate students, early career researchers and experts in neighbouring fields a better understanding of each subject by presenting multiple viewpoints from different lecturers, thus enabling the participants to better engage in the subsequent workshops and seminars. There will also be problem sessions and working groups in the afternoons to expose graduate students to cutting edge research and foster collaborations among postdoctoral fellows, long term participants and winter school participants from all career stages.
