The Career Support Core (CASC) will provide a launching platform for future research leaders that grows and nurtures research lines around the broad theme of daily-life stress and build on the game changers of Stress in Action. The CASC will (1) attract and recruit top-talented researchers, (2) optimise their talent and career development through tailored mentoring, provision of leadership roles within the SiA programme, and an (international) exchange programme, and (3) provide education in e.g. theory, assessment and analytical methods relevant for the SiA programme, thereby boosting the international position of daily-life stress researchers.
