DDLS and WASP announce a joint call for NESTs (Novelty, Excellence, Synergy, and Teams) projects that span across the thematic profiles of DDLS and WASP. A NEST should address a specific strategic high-priority research challenge with international impact and visibility that requires the gathered competence of a multidisciplinary team of investigators in order to be solved. The added value from collaboration between WASP and DDLS, but also within each of the programs, should be clearly emphasized. Scientific novelty, originality and impact, as well as their relevance to Swedish industry and/or society are important.
