[6] In 2011, she was elected as fellow of the Nigerian Academy of Science, the highest scientific organization in Nigeria.

[8] 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 five times more than anywhere else on the planet.

Okeke's research interests include geomagnetism, atmospheric physics, and climate variability.

[5] 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.

In 2010, one of her Female PhD students, Theresa Obiekezie, won an AU-TWAS young scientist Award.
