UPSC have received 9 two-year post-doctoral fellowships from the Kempe Foundation as a continuation of the internationalization project initiated three years ago. The ambition with this program is to stimulate UPSC researchers to initiate close international collaborations with research institutes or universities from other countries. The positions will be distributed through a competitive application procedure within UPSC. The evaluation of the applications will be done by external reviewers on the basis of the scientific quality of the project, the collaboration plan and the CV of the PIs.
