Biography

Prof. Ephraim NgoziErumaka is a native of Ossah, Umuahia North LGA of Abia State. He attended Ossah Central School, Umuahia between 1961 and 1967. He proceeded to Community Secondary School, Isingwufor his secondary education where he obtained his SSCE in 1974. He later proceeded to University of Nigeria, Nsukka for his university education where he graduated in Mathematics in 1980.  His Master’s and PhD degrees were obtained at the Federal University of Technology, Owerri, and the University of Nigeria, Nsukka in the year 1985 and 2002, respectively.
