Prof Imhotep Alagidede

Professor Alagidede is very keen at developing metaleaders through a dedicated programme of mentorship. He is involved in training and coaching people from all walks of life to tap into their inner potential.

The research interest of Imhotep is tilted towards a synthesis of the thesis and the antithesis in all disciplines. He believes strongly in the value of multidisciplinary research, and after retiring as Editor-in-Chief of the African Review of Economics and Finance journal, he became the Grand Editor of the multidimensional publication, the Journal of Indigenous and Ancestral Studies. He is dedicated to finding the balance between the modern and the ancient; the known and the unknown. To this end indigenous knowledge, and how it merges with modern technology is the bedrock of Imhotep’s research trajectory. He is interested in supervising strong PhD candidates in different aspects of indigenous knowledge and its appropriate utilisation, including but not limited to herbs and plants, economic and political systems.
