Biography

Dr Celestin A. Nse is a native of Bamenda, North West Region, Cameroun. He hails from KedjomKetinguh, Cameroun. He attended Government Primary School, Bafoussam between 1974 and 1979. He proceeded to Government High School, Mamfefor his secondary education where he obtained his GCE ‘O’ Level and ‘A’ Level in 1985 and 1987, respectively. He came into FUTO as an undergraduate in 1993 where he graduated with a Second Class Upper Division in Mathematics in 1997.  His Master’s and PhD degrees were obtained at the Federal University of Technology, Owerri, and the University of Nigeria, Nsukka in the year 2000 and 2008, respectively.
