Prof. Joseph Olorunfemi Ojo obtained his B.Eng and M.Eng degree in Electrical Engineering from Ahmadu Bello University, Zaria in 1977 and 1980. He thereafter proceeded to University of Wisconsin, Madison, USA where he obtained Ph.D in Electrical Engineering in 1987 respectively.
On completion of his graduate studies in Wisconsin, he served as a Lecturer in Department of Electrical Engineering at Ahmadu Bello University, Zaria, between 1978 and 1982. In 1982-1988, he was appointed as a Teaching and Research Assistant and Research Associate, Department of Electrical Engineering at the University of Wisconsin, Madison, USA. In 1988, he joined Tennessee Technology University, Cookeville, Tennessee where he rose to become Professor of Electrical Engineering 1n 1998. He was later appointed to the TVA chair of Electrical and Computer Engineering in 2009 to date. Professor Ojo had made significant contributions to the understanding and analysis of dual stator electric machines and power electronic converters. They are now used for high power Megawatt range sensitive renewable power generation, all electric ships and aircrafts. He developed the vector control schemes of the machines, through which the maximization and selection of the air-gap flux results in the attainment of maximum torque. His work, funded by the U.S. Office of Naval Research (ONR), provides the basis for the selection of appropriate motor drives and generators for the proposed U.S. all electric Naval ships and enables the recent exploration of the dual winding induction machine for MW offshore wind power generation in Scotland and marine power generation in China.
Prof. Ojo 1995 research which outline the process of self-excitation and de-excitation of the induction generators, using concepts of system bifurcations have opened up the possibility of understanding the operability regimes and the role of converters in enhancing and regulating generator operations. Research on the application of nonlinear dynamics on the Nigerian Electric Power Systems (Funded by the U.S. National Foundation) has revealed factors leading to perennial voltage collapse, technical reasons why Lagos could not be supplied with adequate power even if there is enough generation and remedial actions to be taken to ensure reliable and adequate power supply in the country. He received the Caplenor Faculty Research Award, Kinslow Award, Sigma XI Research Award and IEEE Industry Application Society Paper Award. He has written many books and has published in several journals.
He is a Fellow, Institute of Electrical and Electronics Engineers (IEEE), Nigeria Electricity Regulatory Commission (NERC)and Institute of Electrical Engineering (IEE) and the Nigerian Academy of Engineering.
