Staff Profile
I am a Senior lecturer at Nnamdi Azikiwe University, Awka, Nigeria and the current Head of Department.
I won several awards/grants including: University Scholar Scheme Award in Nigeria (2000), Dean’s Award of Best Graduating Student (2004), TetFund Travel Grant (to attend International Horticultural Congress, Turkey, 2018), TWAS-SAREP Travel Grant (Kenya, 2019) and Nigeria Academy of Science Conference Grant (University of Lagos, Akoka, 2020).
I am a fellow of Fellow of Orange Knowledge Programme (OKP) Wageningen, the Netherlands, 2022 and fellow of Fellow, Israel’s Agency for International Development Cooperation (MASHAV), Israel, 2018.
My current research is focused on improving shelf life and nutritional quality of solanaceae crops by manipulating soil potassium levels and determining safety and quality of horticultural crops produced with compost.
My research interests include; compost production, plant nutrition, climate change mitigation and adaptation, climate smart crop production, soil moisture conservation techniques and academic writing and publishing.
I authored over 45 publications in the priority areas of horticulture and presented papers in international, regional and national conferences.
I attended workshops on Science Diplomacy online in 2022 by University of Embu, Kenya, Feed the Future Innovation Lab for Legume Systems Research Grant Writing Workshop online by USAID, USA in 2022, Good Agricultural Practices in Turkey, 2018 by International Society of Horticultural Science.
I co-authored a book titled: “Rapid multiplication of cassava propagule” (published on Amazon.com) to equip young people with entrepreneurial skills of cassava propagules development in the real world after leaving school.
