The International Helmholtz Research School of Biophysics and Soft Matter (IHRS BioSoft) at Forschungszentrum Jülich, Heinrich-Heine-Universität Düsseldorf, Universität zu Köln, and Forschungszentrum caesar Bonn offers positions for three-year PhD projects. Scientists in our institutes work in the areas of physics, chemistry, and biology, while the research school provides an in-depth training in biophysics and soft matter. A variety of experimental and theoretical tools enables PhD students to gain deeper understanding of structure, dynamics, and function of complex systems.
