Tobias Innocent Ndubuisi Ezejiofor (a.k.a, T.I.N. Ezejiofor) was born on 21st January 1966 at Aba and hails from Amorka, Ihiala Local Government Area of Anambra State, Nigeria. He had his primary and secondary education at Aba between 1970 and 1975, 1975 and 1980 respectively. Thereafter, he proceeded to the School of Health Technology Aba, wherein 1983 he obtained the diploma in Environmental Health(DEH) of the institution as well as the Public Health diploma(DPH) of the West Africa Health Examination Board(WAHEB) thereby qualifying as a Public Health Officer. Beyond this, Mr Ezejiofor obtained a B.Sc. (Hons) degree in Medical Laboratory Sciences from Rivers State University of Science & Technology, Port Harcourt, Nigeria (1988), an M.Sc. degree in Applied Biochemistry from Nnamdi Azikiwe University, Awka, Nigeria (1997/98), and the degree of doctor of philosophy (PhD) in Environmental Health Biology from the Federal University of Technology, Owerri, Nigeria (2009/10). To cut his professional teeth, Dr. Ezejiofor also schooled at the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria (1990) and the University of Nigeria Teaching Hospital, Enugu, Nigeria (1996) for the Associate and Fellowship of the Medical Laboratory Science Council of Nigeria in Chemical Pathology and Medical Microbiology respectively. He is duly registered and Licensed by both the Environmental Health Officers Registration Council of Nigeria (EHORECON) and the Medical Laboratory Science Council of Nigeria (MLSCN). He is also a Fellow, College of Biomedical Engineering and Technology (FCBET) of Nigeria; and Fellow, West Africa Postgraduate College of Environmental Health (FWAPCEH), as well as a member of several national and international professional and learned societies.
At various times, Dr. Ezejiofor had served in several capacities in different institutions including the Imo State Ministry of Health; Schools of Health Technology at Aba and Amaigbo respectively; University of Nigeria Teaching Hospital, Enugu; Abia State University Medical School (Chemical Pathology); and presently, Federal University of Technology, Owerri, Nigeria where, now a Professor in the Department of Biotechnology, and also a Research Fellow in the institute of Environmental Health and Environmental Justice of the Federal University of Technology, Owerri, he is actively engaged in teaching, research and community services. He is credited with many professional and administrative experience laced with achievements in those capacities. He is a prolific researcher as he finds interest in everything within his environment, though with particular attention to issues bothering on health, safety and environment - an area in which he had published quite considerably in both national and international peer-reviewed journals. Presently, he is the Vice President of the Environmental Health Scientist Association of Nigeria (EHSAN), a committed and active member of the National Association of Medical Laboratory Scientists of Nigeria (NAMLSN). He has earned membership and fellowship of several national and international professional bodies and learned societies. He is on the editorial board of some journals, and also serves as a reviewer to several others. He had attended and presented papers at several local and international conferences and workshops.
With a background that spans through almost all aspects of Medical/Biomedical and public health sciences, Professor Ezejiofor is ready and available to undergo any further tutelage (as may be needed/required for certain positions), and/or to embark on enterprising research that would be of relevance towards resolution of the many challenges/problems beseeching humanity, particularly those that requires application of knowledge in the realms of biological, biotechnological, biomedical, medical and public health sciences.
Professor Ezejiofor is a Christian of the Catholic denomination. He is married to Dr (Mrs.) Favour Anthonet Ndidiamaka Ezejiofor and the marriage is blessed with 4 children- 2 boys and 2 girls.
