The University of Strasbourg is considered to be an associated partner linked to CNRS. All PhD candidates hired by CNRS at Strasbourg have their PhD diploma awarded by the University of Strasbourg, as per usual in the case of Joint Research Units (JRU). Inherent to the structure of JRUs, resources are received from both CNRS and UNISTRA through the use of the infrastructure and the involvement of permanent staff. The University of Strasbourg has hosted 18 Nobel Prizes since its founding, of whom four are still active.
