The aim of the meeting is to bring together Italian scientists, working in the fields of theoretical, experimental and numerical approaches for soft, heterogeneous and biological materials. To this end, ten different Prin Projects (Prin 2022, Prin PNRR 2022), all focussed on these scientific fields, will have their kick off meeting during this conference. The aim is not only scientific, but also to promote new collaborations and synergies between the different groups that will work in the next years in these Prin projects. Beyond the discussion of the scientific program of the projects, young scientists involved in these activities have been invited to present their results and perspectives. A round table will also be devoted to coordinate the experimental activities and the scientific activities of the young researchers involved in the projects.
