Proyecto Interuniversitario entre las universidades de La Habana, Milán y Alicante como estrategia de aprendizaje en estudios de Doctorado.

University students, in general, benefit academically in a unique way when they participate in a multidisciplinary, interdisciplinary, and interuniversity project. This "meaningful learning" involves establishing a solid knowledge base at different university levels, especially in doctoral studies. This contribution analyzes a specific experience surrounding an academic teaching and research project developed in Havana, in which doctoral students from the universities of Havana, Milan, and Alicante participated. This project focused its work on the context of Havana and the Bay, with the participation of the knowledge areas of sociology, architectural construction, urban planning, tourism, and heritage conservation. Through two complementary activities carried out in February and March 2025, doctoral students were able to design and develop fieldwork research projects: the first entitled "Inhabiting the City of Havana: Health, Well-being, and Sustainability" and the second "Sustaining the Bay: Collaborative Strategies for Preservation and Urban Development in Havana.” As a result of the activities, common problems have been identified in the different cities of the participating universities. Under the name "Cities of Contrast," the interuniversity project opens a path for collaboration between professors and students in the research of shared current problems.
