The Government Office for Science offers UK Intelligence Community (IC) Postdoctoral Research Fellowships to outstanding early career science or engineering researchers. These Fellowships are designed to promote unclassified basic research in areas of interest to the intelligence, security and defence communities.
One round of applications is held annually. Members of the IC identify research topics and the Research Fellows work locally with University Research Advisors to develop and submit research proposals that align with the topics. Info on the topics here.
The Fellowships are aimed at early career researchers from all branches of science and engineering who have up to four years postdoctoral experience. Each application for the Fellowships is capped at a maximum grant of £200,000 over a 2-year period.
