Chidi Donatus Okereke a native of Umuchoke Umunumo in Ehime Mbano local government area of Imo State Nigeria embraced love for nature, dexterity and culture early in life. As a primary school pupil he was exposed to handicraft and simple technology of making compost manure.

Despite the setback of the civil war between Nigeria and Biafra (1967 -1970), he went successfully through the crucible of secondary, post secondary and university education with strong grounding in the sciences.

Before entering Ahmadu Bello University (ABU) Zaria in 1977, Chidi Donatus Okereke had taught at Aquinas Secondary School Osu as a tutor in 1976 with Higher School Certificate obtained at Federal Government College, Port Harcourt. He graduated from ABU Zaria in 1980 with First Class degree in Agric. Engineering (Soil & Water Engineering) and did his National Youth Services Corps (NYSC) at Upper Benue River Basin Development Authority Yola before joining the services of FUTO in 1981 as Assistant lecturer.

Chidi Donatus Okereke also holds M.Sc. Water Resources Technology, Civil Engineering of the University of Birmingham UK 1983 and PhD Public Health Engineering, Civil Engineering of Federal University of Technology Owerri  (FUTO) 2002.

He is a COREN Registered Engineer R4747 Council for Regulation of Engineering in Nigeria 1991 and a Fellow Nigerian Environmental Society (FNES).

His research works span across areas of Biowaste and biomass to energy, water quality control, climate, environmental pollution control, soil conservation and R&D of devices/technologies in Environmental Engineering/Water resources. He has many publications and patent to his credit.


Chidi Donatus Okereke rose to the rank of full professor (Professor of Environmental Engineering) in 2003.

As a university teacher, he taught and supervised projects/research of many undergraduate and postgraduate students some of who are gainfully serving society in various capacities as PhD holders, Professors and in top echelon of their chosen areas of human endeavour.


He held positions such as

  • Head of Department, Environmental Technology, FUTO (1998-2001; 2005-2006)
  • Director of Office for University Development (OUD) (2006-2008)
  • Director, Central Instruments Equipment Centre FUTO (2017- 2021)
  • Dean, Postgraduate School FUTO (2008-2012)
  • Chairman, NUC Accreditation Environmental Science ‘A’ in Northern Zone, team for ATBU (2010)
  • National Member, Tetfund R&D Standing Committee
  • External Examiner to a number of universities in Nigeria.


Prof Chidi Donatus Okereke was Visiting Academic/Professor to CUTEC and an alumnus of DAAD Germany.  He is married to Dr Mrs Stella Ngozi Okereke and their marriage is blessed with 5 children.
