Welcome to 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 is non-Swedish 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. UPSC is therefore a highly dynamic institute. The iUPSC welcome platform provides services and support for new arrivals and visitors. This includes help with housing, work permits, bank contacts, etc..
