A defining characteristic of life at the DCEXS is the supportive atmosphere and the high level of interaction among students, faculty and postdoctoral fellows on a scientific level, as well as cultural and socially. The department is composed of people from a wide range of places in Spain. We are starting to have a significant fraction of scientists and students from abroad, which gives rise to a distinct international and cosmopolitan flair. A wide range of scientific lectures, conferences and cultural events bring people together on almost a daily basis. Moreover, we participate in all scientific and social events organized by the PRBB such as regular seminars, beach-volley championship, etc
