I was born on the 20 September, 1959 in Ila-Orangun, Osun State, Nigeria. I obtained the West African School Certificate in 1976; Higher School Certificate in 1978 and obtained B.Sc., M.Sc., and PhD. degrees from the University of Ibadan in 1982; 1985; and 2003 respectively. I won the Pfizer prize for the best student in Crop Science and Agricultural Mechanization, University of Ibadan, 1982.
I started work as Secondary school teacher at Abadina College, UI, Ibadan in 1983. I have worked with the International Livestock Centre for Africa (Ibadan) as Chief Research Assistant and the International Institute of Tropical Agriculture (Ibadan) as Research Associate and Consultant before I joined Ladoke Akintola University of Technology, Ogbomoso, Oyo State, Nigeria as a lecturer in 2004.
I have taught courses in Soil fertility, Farming systems, Field experimentation and statistics, Plant nutrition among others since 2004. In have supervised several undergraduate and post graduate students.
I have served as Deputy Dean, Head of Department, Member, Appointments and Promotions Committee among others at the Ladoke Akintola University of Technology, Ogbomoso.
I am a member of the following professional bodies; Soil Science Society of Nigeria, Agriculture Society of Nigeria, African Network for Soil Biology and Fertility (AfNET), International Society for Organic Agriculture (ISOFAR) and Association of Organic Agriculture Practitioners of Nigeria (NOAN).
I have trained many students at both the undergraduate and post graduate levels. I have attended national and international conferences. I have published more than sixty (60) scientific articles in reputable local and international journals.
