Dr. K. Obeng-Antwi attended Prempeh College, Kumasi, and holds a B.Sc. (Hons.) degree in Crop Science from Kwame Nkrumah University of Science and Technology, Kumasi, Ghana, MSc in Plant Breeding from the University of Guelph in Canada, and Ph.D (Agriculture) from University of Reading, UK. His research interests are varied, ranging from maize population improvement, through inbred line development and testing in crosses and hybrid development. Genetic diversity in maize germplasm, especially landraces, is another area of his interest. Currently, he is involved in the development of hybrid maize varieties for the Forest and Forest-Guinea Savanna Transition zones of Ghana. He is also leader of a team of scientists at the Crops Research Institute which is responsible for running nationally-coordinated trials which have the objective of identifying promising maize varieties for on-farm testing and eventual release for commercial production in Ghana.

He was a research assistant at the Maize Breeding Section of the Crop Science Department during his MSc programme at University of Guelph. During his PhD studies, he spent one year as a research fellow at the International Institute of Tropical Agriculture in Ibadan, Nigeria.

Dr. Obeng-Antwi has a good number of peer reviewed publications in international and local journals. He has travelled extensively, conducted research in both local (CSIR-Crops Research Institute and CSIR-Savanna Agricultural Research Institute). He has participated in several national and international scientific conferences and workshops in Africa (Ghana, Benin, Nigeria, Kenya, Burkina Faso, South Africa and Zimbabwe) and Mexico (Central America.
