Professor Badejo holds a Bachelor of Science Degree in Biology, a Masters of Science in Zoology as well as a Doctorate in Zoology from Obafemi Awolowo University, Ile-Ife. In addition to these degrees, he also earned a distinction in the Post-Doctoral Diploma course in Environmental Science and Technology of the International Institute for Hydraulic and Environmental Engineering (IHE), which is now known as UNESCO-IHE in Delft, The Netherlands - an acknowledged European Centre of academic excellence.Professor Badejo started his career as an Entomology teacher and researcher in Soil Ecology in the Department of Zoology, Obafemi Awolowo University in 1981 where he rose steadily through the ranks to become a Reader in 1995 and a Professor in 1998. He is a distinguished Professor of Zoology who served as the Dean of the Faculty of Science in Obafemi Awolowo University, Ile-Ife from August 2003 to July 2007. As the Dean of the Faculty of Science, Professor Badejo not only encouraged academic discourse across departments, he also restored hope in hardworking young academics. Prof. Badejo was a Senior Research Advisor with Shell Petroleum Development Company (SPDC), Eastern Division before he was appointed the pioneer Vice Chancellor of Wesley University of Science and Technology, Ondo (WUSTO) in Ondo State in 2008. The Governing Council of WUSTO gave him a second term of five years with effect from April 01, 2013 based on satisfactory performance. As a pioneer Vice-Chancellor, Prof. Badejo and his management team took giant strides in building a university of science and technology from the scratch. The rate of infrastructural development in this university is enviable as buildings sprang up by the day at a rate that would make other new universities envious. In May 2015, after 7 solid years of hard work uninterrupted by annual leaves, Prof. Badejo passionately appealed to the Governing Council of Wesley University to allow him to end the tenure for a well-deserved rest. Prof. Badejo is now spending his sabbatical leave from Wesley University as a Visiting Professor in Ondo State University of Science and Technology (OSUSTECH) in Okitipupa.
A scholar of International repute, Prof. Badejo has up to date published five books and 73 academic papers in local and international journals in the broad field of Soil Entomology, Acarology, Ecotoxicology of Microarthropods and Environmental Studies in Agriculture. He also has to his credit 17 workshop papers and 11 technical reports, thus making a total of 101 academic publications, 36 of which he published after becoming Professor.
As a Georg Forster Fellow of the Alexander Van Humboldt Stiftung at the Museum of Natural History in Karlsruhe, Germany from November 2000 to July 2002, Professor Badejo provided names to 22 species of Oribatid mites he collected from Ile-Ife, Ibadan and Rio de Janeiro in Brazil, thus putting the name of Nigeria on the world map of Acarology, a field of Biology where many taxonomists avoid due to the tiny size and complex morphology of members of this group of arthropods. In recognition of his contribution in the field of Acarology (study of mites), he was one of three Nigerian Acarologists listed in the Directory of Acarologists in the world in 1992.
Prof. Badejo is the Editor-in-Chief of an International Journal which was rated as a journal of Prospective International Standard in the Quality assurance of Publications of Nigerian Academics carried out by the National Universities Commission in 2005, barely two years after he established this journal. The journal has published eleven volumes up to date. Professor Badejo was rated among the top ten researchers in Obafemi Awolowo University between 1995 and 2005 in a recent webometrics ranking by the World Bank.
In 2002, Prof. Badejo published a book titled “Insects at War”. The book is an interesting prose where insects such as cockroaches, termites and ants are the major characters. While it exposes many aspects of life and living, ranging from domestic to political levels, it also enlightens the reader on several aspects of insect morphology and behaviour. In the year 2012, Prof. Badejo launched two other literary works. One is a play titled Inmates where ‘he adopted the trope of the prison to reflect the sore points of a nation that is suffering the pangs of disunity, political instability and underdevelopment, even 50 years after independence’. The other is a compilation of his weekly admonition to his students in WUSTO titled My Commandments which is “…a chronicle of moral regeneration efforts of an academic in the Ivory Tower”.
Prof Badejo is a Fagunwa scholar. He delivered the 7th D.O. Fagunwa Foundation Lecture on December 07, 2012 and he was one of the resource persons who as a Fagunwa Scholar presented a paper on ‘The Zoologist in Fagunwa’ in August 2013 to commemorate 50 years anniversary of D.O. Fagunwa’s demise.
Prof. Badejo belongs to many professional bodies among which are the Association of Tropical Biologists (ATB); Nigerian Environmental Study/Action team (NEST) since 1991; Society of Ecotoxicology and Environmental Safety (SECOTOX) since 1992; Ecological Society of America (ESA); International Congress of Ecology (INTECOL); Nigerian Society of Environmental Management (NISEM). In August 2009, Prof. Badejo was elected a member of the Board of International Association of Soil Zoologists at the XVth International Colloquium on Soil Zoology in Curitiba, Brazil.
During the seven years of meritorious service as Vice-Chancellor, Prof. Badejo, a motivational speaker, delivered lectures on various topics at various academic and non-academic fora. Prominent among these public lectures are the following titles:
Prof. Badejo is a good mixer who is widely acknowledged in Obafemi Awolowo University (OAU) in Ile-Ife as well as Ondo community for his good human relations, wealth of experience, foresight, agility, doggedness, dedication to duty and commitment to the progress of hardworking university staff.
