The project aimed to connect higher education with applied research and to systematically strengthen the capacities of participating institutions from different regions—Europe and Latin America—through the mobility of doctoral candidates and academic staff of University of Chemistry and Technology, Prague and University of Magallanes (Chile). We focused on developing professional skills, sharing know-how, and producing joint outputs, including research in marine biotechnology and bioprospecting. Specifically, we expanded cooperation toward the study of sub-Antarctic and Antarctic macroalgae from the Magallanes region, whose unusual conditions (polar day/night, low temperatures) are reflected in a unique chemical composition with potential for healthcare and industrial applications—from UV-blocking compounds to antimicrobial, anti-inflammatory, and wound-healing effects. At the same time, the project enhanced the international visibility of both universities and fostered long-term partnerships: it built on existing joint activities and moved toward sustainable collaboration in research and in teaching based on inquiry-based learning (joint seminars, theses, summer schools, and reciprocal stays of academics and doctoral candidates).
