The Alexander von Humboldt Foundation grants the Georg Forster Research Fellowship to postdoctoral and experienced researchers who are contributing to sustainable development. Researchers in all disciplines from developing and emerging countries can apply who have above-average qualifications. The Fellowship enables them to conduct their own research at various stages of their career in collaboration with a host at a German research institution of their choice. Fellowships may last from 6 to 24 months and can be divided into up to three stays within three years. Applications are reviewed for this program meets every February, June, and October.
