Prof Ebenso obtained his PhD in Physical Chemistry from the University of Calabar, Nigeria and has been lecturing in the university system since 1990. He started his university teaching career at the University of Calabar, Nigeria. He was the Acting Vice Rector (Research and Planning) and  the Executive Dean of the Faculty of Natural and Agricultural Sciences at the entire North-West University in South Africa – Dec 31^st 2019. He then took up appointment as Research Professor at the University of South Africa (Ist Feb 2021 till date).

His research interest span through physical chemistry (electrochemistry, kinetics, adsorption, thermodynamics of corrosion - and using some quantum chemical methods like density functional theory (DFT) and other semi-empirical methods to study corrosion inhibition efficiencies of compounds; extensive quantitative structure activity relationship studies (QSAR); Molecular dynamics/ Monte Carlo Simulation studies. He has also published papers on electrochemical sensors for detection of neurotransmitters and thermodynamics of solutions.

He is a member of many learned and professional societies namely Chemical Society of Nigeria (MCSN)., American Chemical Society (MACS)., NACE, International Corrosion Society, International Society of Electrochemistry, South African Chemical Institute (M.S.A. Chem. I.), South African Council for Natural Scientific Professions (SACNASP) (Pri. Sci. Nat), Fellow, Royal Society of Chemistry, UK (FRSC) and member of Academy of Science of South Africa (ASSAf).
