In our paper, we discuss international mobility of highly skilled professionals in the Swedish medical field: medical molecular biologists and physicians who had been trained and worked in Sweden, then spent some time working abroad and returned to Sweden. The aim is to study the returners’ reflections about mobility, the knowledge gained during work in different settings and possibilities to apply the newly gained knowledge and experiences at Swedish working places. This is investigated through three sub projects, focusing on: 1. Molecular biologists, depended on international mobility for successful research, 2. Specialist physicians, involved in both research and clinical practice, for whom mobility is supposed to enhance both, 3. Specialised physicians working as volunteers for international organisations, gaining skills on work under difficult circumstances and with limited resources. The study is based on ethnographic methods, primary in-depth interviews. Cultural analysis is combined with theories on knowledge, Bourdieu’s theory of capital and gender perspective. In the presentation, we shall focus on the concept of knowledge and skills; what knowledge is gained through international mobility and how is it made use of and recognized at the Swedish work places?
