By February 2014, he had published 125 articles in leading scientific journals (such as ChemComm, J Mater Chem, Energy Environ Sci, PCCP, ACS Appl Mater Interfaces, Langmuir, Electrochem Commun, and Electrochim Acta) as well as six book chapters. He was cited 2 674 times and holds an H-index of 30 and i10-index of 74 (indicating that each of his 74 papers has been cited at least 10 times). Between 2006 and 2010 four of his publications were recognised by the Royal Society of Chemistry and Elsevier Publishers as “top hottest articles”.

Prof Ozoemena is the Principal Researcher and Research Group Leader of the Electrochemical Energy Technologies at the CSIR Materials Science and Manufacturing Division. His research is highly interdisciplinary, spanning several areas of Materials Science and Electrochemistry. This includes among others,  synthetic inorganic chemistry and electrochemical sensing to electro catalysis and electrochemical energy systems. Presently, his research focus is on the electrochemistry of nanostructured materials and redox-active N4-macrocyclic metal complexes (e.g. metallophthalocyanines) with a view to establishing their potential applications in the development of electrochemical energy systems (i.e. fuel cells, electrochemical capacitors, and lithium/sodium ion batteries, as well as dye-sensitised solar cells).

He obtained his PhD degree in Chemistry in 2003 at Rhodes University, after which he completed postgraduate qualifications in Management Development (MDP), as well as in Higher Education (PGCHE) at the University of Pretoria. Furthermore, he is an Extraordinary Professor at the University of the Western Cape. Prof Ozoemena is currently a B-2 rated NRF researcher. Besides being awarded  the “Exceptional Young Researcher Achievement Award” by UP in 2009, he also received the “Outstanding Young Academic Award” from Nigeria (Office of the Nigeria High Commissioner in South Africa) in 2009,  and the CSIR “Research Excellence Award” for 2012.

Prof Ozoemena was admitted as a Fellow of the Royal Society of Chemistry (FRSC) (UK) in May 2011 and attained the status of Chartered Chemist (CChem) of the Royal Society of Chemistry (UK) in February 2008. He also attained the  Chartered Scientist (CSci) qualification of the Science Council (UK) in 2008. He is a member of the editorial board of several scientific journals, (including Electrochemistry Communications), as well as Associate Editor of Materials Focus, and served as Guest Editor of Electrochemical Acta and Journal of Porphyrins and Phthalocyanines.
