The International Union of Geodesy and Geophysics (IUGG) has awarded the inaugural (2022) IUGG Commission on Mathematical Geophysics (IUGG-CMG) Vladimir Keilis-Borok Medal to Frederik J Simons  for "his outstanding contributions to mathematical geophysics and development of cutting-edge mathematical methods in geoscience data analysis."

The Vladimir Keilis-Borok Medal was established in 2021 to recognise middle career scientists, who made important contributions to the field of mathematical geophysics. The aim of the Medal is to honour the legacy of Keilis-Borok ­ a visionary science leader and organiser, prolific mathematical geophysicist, the CMG founder, and former IUGG President in promoting transformative scientific advancement and selfless leadership.
