Chris Obioma Nwoko,   PhD


B.Sc (Calabar), M.Sc, PhD( Ibadan)
Environmental Biology(Restoration Ecology)



Brief Professional Background

Dr. Chris Obioma  Nwoko was born in Abia State, Southeastern Nigeria in 1971. Educated at University of Calabar South-South Nigeria were he obtained B.Sc degree (Botany) in 1995. He proceeded to the University of Ibadan Southwestern, Nigeria for his M.Sc and PhD degrees (Environmental Biology) in 1998 and 2010, respectively. He has consulted for private and government agencies on environmental issues such as Impact Assessment Study, Ecosystem restoration and waste management. He was Environmental Consultant on World Bank (Assisted Projects) for FADAMA III in Imo and Abia States of Nigeria from 2014-2015.   He is an Associate Professor and Former Head, Department of Environmental Technology. He has over 28 publications to his credit in highly rated peer-reviewed journals nationally and internationally. He has held many leadership positions e.g coordinator of exams, class advisors and patron of some voluntary organizations in Nigeria.   His current research interest is on enhancing Soil Organic Matter (SOM) mineralization to match crop needs, the role of Arbuscular mycorrhizal fungi in soil contaminant removal and ways of sequestrating carbon as a strategy for abating climate change. Dr. Nwoko is a member of Nigerian Environmental Society, Ecological Society of Nigeria and International Biometric Society.
