Scientists from and working in developing countries, who want to undertake a two month visit in 2023 at their alma mater (but not only) in Europe (excluding Italy), North America or a more advanced developing country, should apply to the APS-EPS-ICTP Travel Award Fellowship Programme (ATAP).
Four grants are available for use in 2023, and the Programme is now accepting applications.
