Every year, universities worldwide open their doors to international students to join their research programs. Thousands of students move from one country to another with the dream to pursue higher education and increase their career opportunities. As a result, universities are cultural hubs that gather students and researchers from different backgrounds, who provide a diverse and enriching environment while embracing newcomers with their institutional values and culture. For PhD programs in Europe, students can participate in public engagement and outreach activities, a practice that is becoming highly encouraged and, in some cases, is required. Many research projects, funded with public funds from national science organizations, are required to keep the public informed about their work and research findings through public engagement activities. Moreover, the culture of science dissemination is part of university life, and it can also be led by student societies or university organizations that are not linked to specific research funds. Students join these projects as part of their professional development, gaining skills to engage with the general public.
