Johannes Geiss Fellowship 2025

The International Space Science Institute (ISSI) in Bern, Switzerland invites applications for the 2025 Johannes Geiss Fellowship (JGF25). With this fellowship ISSI honours the memory of Johannes Geiss, the founder of ISSI, and his contributions to the space sciences.

The fellowship aims to attract internationally renowned scientists to make a significant contribution to the ISSI mission by pursuing ambitious independent research, in any of the disciplines that are part of ISSI’s core mission:  Astrophysics, Heliophysics, Planetary Sciences and Earth Science.

The Johannes Geiss Fellow is expected to participate in ISSI activities and to collaborate with ISSI’s scientific staff and visitors, as well as with research institutes in Switzerland. The Johannes Geiss Fellow is invited to give public lectures in close collaboration with the Pro ISSI Association.

The JGF provides a stipend covering travel costs, an apartment for the duration of the stay and living expenses for a stay at ISSI Bern of up to 6 months. ISSI can host JGFs either for a single extended visit (e.g., during a sabbatical) or for several shorter duration visits.
