The article is based on a qualitative study (qualitative interviews, observation in the laboratory and consultation to document sources) investigating the contents of this international movement, from the more institutional experience, such as graduate school abroad, to more informal mobility, such as participation in seminars and other forms of exchange of short duration. This study helps understand the effects of these temporary migrations in personal and professional accomplishments, career paths, as well as changes in their research practices and establishment of international research networks.
To discuss these issues, we start from the empirical study of the Human Genome Research Center. Cutting the discussion to a specific area of knowledge and to a specific institution is necessary, because the scientific activity can not be treated uniformly, there are different configurations according to the knowledge area, institution,etc. We seek to understand how the general trends of the internationalization of science are expressed in a national context and in a specific area of knowledge.
