Francisca Okeke is a Nigerian scientist and Professor of Physics at the University of Nigeria.Okeke has dedicated much of her career to studying the ionosphere and the “equatorial electrojet phenomenon.” Energized by the sun, the electrojet is a river of electric current that traverses the globe eastward around the dip equator and causes the magnetic field at the dip equator to vary almost fives time more than anywhere else on the planet.She was named L'Oréal-UNESCO For Women in Science Awards Laureate for Africa in 2013 for her significant contributions to the understanding of daily variations of the ion currents in the upper atmosphere which may further our understanding of climate change.
