Okeke's research interests are Geomagnetism, atmospheric Physics, and climate variability.[1]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. (The dip or magnetic equator differs from the equator by a few degrees, as the Earth's magnetic north pole is different from what we generally think of as the north pole.)

Okeke's research on how solar activity in the ionosphere affects the Earth's magnetic field could lead to a better understanding of climate change and help pinpoint sources of dramatic phenomena like tsunamis and earthquakes. She has successfully supervised 12 Ph.D. and about 28 M.Sc students.
