Johannes Geiss Fellowship

The Johannes Geiss Fellowship (JGF) was established to attract to ISSI international scientists of stature for extended stays of up to 6 months duration. The Fellows will make demonstrable contributions to the ISSI mission and increase ISSI’s recognition through their presence. In doing so they honour ISSI’s founding director Johannes Geiss for his wide-ranging contributions to space science in general, and to ISSI in particular. Geiss Fellows are allocated one of ISSI’s visitor apartments and office space of their own for the duration of their stay.
