Welcome to the UPSC! We are an international institute. More than 40 nations are represented (47 nations 2016) and the working language is English. About half of our staff members are non-Swedes and we recruit researchers from all over the globe. Post-doctoral fellows have the most diverse nationalities, but also our PIs, graduate and undergraduate students represent many different nations. Consequently, the structure of employed staff and students at UPSC is highly dynamic. The iUPSC welcome platform provides services and support for new arrivals and visitors. This includes help with housing, work permits, bank contacts, etc..
