EMBO Short-Term Fellowship
EMBO Short-Term Fellowship funds research exchnages of up to three months between laboratories in eligible countries. Awarded applicants can stay on their research visit for an additional three months (maximum), however, EMBO will not provide funding for this extended period. The aim is to facilitate valuable collaborations with research groups applying techniques that are unavailable in the applicant's laboratory. Short-Term Fellowships are not awarded for exchanges between two laboratories within the same country. Short-Term Fellowships are intended for joint research work rather than consultations. The fellowships cover travel plus subsistence of the fellow only and not of dependents. More information about the EMBO foundation and the Travel Grant here.
