A defining feature of life at PUMPkin is the high level of interaction between institutions, departments and people. Collaboration and interaction among faculty members, postdoctoral fellows, and students - at a scientific level, as well as socially - are set in a collegial, supportive atmosphere. PUMPkin is organized on the basis of several departments from Aarhus University and the University of Copenhagen bringing a dynamic interdisciplinarity to the Centre. People from a wide range of professional areas and countries form a vibrant international and cosmopolitan community. We exchange ideas and work together on a daily basis across departments and research groups in laboratories, during courses and conferences, and in more informal venues as lunch rooms and university bars.
