The aim of the project is to support a top scientist in reintegration activities within his home institution. The inclusion and creation of conditions to retain excellent researchers in the European research environment, and in particular in the organisation of the beneficiary, contributes greatly to the further development of excellence of both the researcher himself and the research carried out at the IOCB. At the same time, there are benefits in the form of support for international cooperation through links of the researcher to previous workplaces.
