Visiting Scientists

Visiting Scientists

As part of the NWP SAF project we have an ongoing visiting scientist programme. This programme allows scientists from institutions that are not SAF members to participate in the activities of the SAF, either as Visiting Scientists or as Associate Scientists, through appropriate projects in their home institutes. If you are interested in joining us for e.g. 1-6 months to work on one of our research projects please feel free to contact us via the Helpdesk.
