Chiedozie is a Nigerian, who is the Assistant Director and Head of Cassava Breeding at the National Root Crops Research Institute (NRCRI), Umudike, Nigeria. NRCRI’s Cassava Research Programme coordinates the development of superior cassava varieties and the national pre-release varietal trials conducted in all agroecologies of the cassava growing areas of Nigeria. Chiedozie has numerous publications in cassava and yam breeding and genetics in peer reviewed journals. He also pioneered and supervised the introduction of molecular marker assisted breeding for important traits in cassava at NRCRI.Between late 2005 and fall 2007, Chiedozie was a postdoctoral researcher in the Cassava Genetics Laboratory of the International Center for Tropical Agriculture (CIAT), Colombia. There he worked on the introgression of delayed post-harvest physiological deterioration (PPD) genes from Manihot walkerae (a wild relative of cassava) into cultivated cassava for the BioCassava Plus project. He also investigated the genetics of inheritance of the delayed PPD trait.

The two main foci of his research are breeding for resistance to the major pests and diseases of cassava, such as the cassava mosaic disease, and the biofortification of cassava roots with beta carotene.
