Francisca Okeke is a physicist who studies the ionosphere as well as the earth magnetic field, particularly the equatorial electrojet episode.

In her research she focuses on the daily variation of the ionic currents in the upper atmosphere as well as geomagnetism and climate variability. For her impactful discoveries, she was awarded the L’Oreal-UNESCO for Women in Science Award.

Okeke's research brings us closer to understanding how big natural events such as tsunamis and earthquakes occur, since the solar ionosphere activity impacts the earths equatorial electrojet episode. These investigations could help explaining the occurrence of such natural phenomenons as well as their strength.
