The IMPRS on Multiscale Bio-Systems is a graduate program at the Max Planck Institute of Colloids and Interfaces, which is located in Potsdam Science Park. Young talented doctoral students can work on a challenging research project and develop their scientific communication and management skills. The school addresses the fundamental levels of bio-systems as provided by macromolecules in aqueous solutions, molecular recognition between these building blocks, free energy transduction by molecular machines as well as structure formation and transport in cells and tissues.
