EMBO Postdoctoral Fellowships support excellent postdoctoral researchers throughout Europe and the world for a period of up to two years. International mobility is a key requirement. EMBO considers a first-author refereed preprint equivalent to a first-author publication as one of the eligibility and assessment criteria for the EMBO Postdoctoral Fellowship scheme. EMBO Programmes and activities are about researching the mechanisms of life at all levels, from single molecules to organisms and ecosystems. The fellowship includes a salary or stipend, a relocation allowance, and support for fellows with children. Awardees can attend an EMBO Laboratory Leadership course and become part of the global network of EMBO Fellows.
