Engr. Prof. Ayodele Samuel Onawumi was born some five decades ago in Ibadan, Oyo state. The young Ayodele completed his secondary education in 1985 and proceeded the same year to The Polytechnic, Ibadan. He however did not complete his training in the polytechnic because he was given an admission to the University of Ibadan in 1986 to study Industrial Engineering. He was in the University between 1986 and 1991 where he bagged his Bachelor of Science in Industrial Engineering. As a young brilliant graduate, He had his NYSC compulsory service at the Ahmadu Bello University, Zaria, where he served as a Graduate Assistant in the Department of Mechanical Engineering between1991 and 1992. Between 1993 and 1994, young Ayodele joined his Alma Malta, the Department of Industrial and Production Engineering, University of Ibadan, as a Teaching Assistant while simultaneously pursuing a degree of Masters of Science, Engr. Ayodele Samuel Onawumi registered with COREN in 2002 and thus qualified to practice engineering in Nigeria. He joined the service of LAUTECH as Lecturer II in 1997 and progressed steadily in his chosen carrier till he became an Associate Professor in 2013. He bagged his Doctor of Philosophy (PhD) in Mechanical Engineering in the year 2009 at the Ladoke Akintola University of Technology (LAUTECH), Ogbomoso. As an academic, Engr. Prof. Onawumi has to his credit, over sixty (60) publications in reputable international and national journals with good impact factor. He has been as associate professor in a number of Universities in the country. He served as reviewer of some academic journals and conference proceeding such as Science Focus (an International journal domicile in LAUTECH Ogbomoso), LAUTECH Journal of Engineering and Technology (LAUJET also domicile in LAUTECH Ogbomoso).
