Collaboration with other national research groups is a fundamental pillar of CIDE's scientific strategy and responds directly to Actions 1 and 2 of the CIDE Strategic Plan 2024 and 2027 (“Develop Synergistic Research Programs” and “Improve the success rate in competitive calls for national projects”). In addition to the numerous specific collaborations, Associated Research Units are established that allow us to strengthen our research areas and take advantage of the scientific resources between research groups in a more efficient way.
