Francisca Nneka Okeke

Francisca Nneka Okeke is a Nigerian physicist. She is a professor of physics at the University of Nigeria, Nsukka and first female head of a department in the university. Due to her research in physics and space science, the International Astronomical Union (IAU) named Asteroid 149831 Okeke after Professor Okeke, in August, 2025.

Biography Francisca Okeke is from Idemili North in Anambra State. She earned a Bachelor of Science in physics (1980), a Master of Science in science education (1985), a Master of Science in applied Earth geophysics (1989), and a Ph.D. in ionospheric geophysics (1995), from the University of Nigeria. She carried out her postdoctoral work at the University of Tokyo, Japan.

Okeke was the head of Department of Physics and Astronomy at the University of Nigeria, Nsukka from 2003 to 2006 and was the dean of the Faculty of Physical Sciences from 2008 to 2010. She was the first woman to hold both positions. Additionally, Okeke was the first female professor of physics in the eastern part of Nigeria.

Scientific research Okeke has dedicated much of her career to studying the ionosphere and the "equatorial electrojet phenomenon."

She has successfully supervised 12 Ph.D. and about 28 M.Sc. students. In 2010, one of her Female PhD students, Theresa Obiekezie, won an AU-TWAS young scientist Award.

Awards Okeke was named L'Oréal-UNESCO For Women in Science Awards Laureate for Africa and Arab States 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. She was cited as one of the Top 100 most influential Africans by New African magazine in 2013.

Personal life Okeke married a physicist, Pius Nwankwo Okeke, at the age of 18, and they have six children.
