RIKEN is currently accepting applications for the FY 2016 Special Postdoctoral Researcher (SPDR) Program, from young, creative, independent researchers who will be a powerful force in furthering RIKEN’s research activities.The Foreign Postdoctoral Researcher (FPR) program launched in 2007 has provided talented young foreign scientists with the same kind of opportunities as the Special Postdoctoral Researcher (SPDR) program which was primarily targeted at young Japanese scientists. Starting from FY 2016, the two programs will be merged into a new SPDR program.

Qualified candidates of all nationalities are welcome to apply. Please see below for details.
