PhD students will learn how a biological problem can be tackled by an integrated approach, from atoms to the whole organism, and how physics contributes to model biological processes. Several topics will be covered: cell and tissue morphogenesis, role of membranes: remodeling and transport, concepts from physics applied to biology, state-of-the-art experimental approaches, links between cellular and structural biology. Concepts and methods will be illustrated with two research fields: Plant morphogenesis from gene to flowers, and Exocytosis, morphology and transport at the synapse.
