INTERNATIONAL DAY ON TRAINING, CO-CREATION, AND EXCHANGE OF EXPERIENCES IN CITIZEN SCIENCE The event will consist of several workshops, debates, talks, and outreach activities. We are convinced that these diverse activities will bring up an outstanding opportunity to enhance and give more visibility to the scientific talent, and to the frontier science and citizen science who are led from Europe and beyond. This socially inclusive and transversal event will also promote scientific careers in young people and aims to foster the visibility of women in science in leading positions.
