The Data Science and Systems Complexity COFUND Doctoral Programme (DSSC COFUND) at the University of Groningen offers 10 early stage researcher (ESR) positions co-funded through the Marie Sklodowska Curie COFUND action under the European Commission’s Horizon 2020 Work Programme. The DSSC aims to train highly skilled graduates who will use state of the art data methodology to understand the behaviour of complex systems and who can handle data and complexity problems for society at large.
