Background and other Interests:

I obtained my BSc (Hons) from the University of Maiduguri, in Nigeria (http://www.unimaid.org); went on to study for MSc at Aberdeen (http://www.abdn.ac.uk), Scotland, and obtained my PhD from The University of Adelaide (http://www.adelaide.edu.au ), Australia.  In order to further develop my teaching I undertook studies towards a Graduate Certificate in Higher Education, which I completed over 2006 at the University of New England, Australia.  During the period after my BSc Honours, I spent 12 years teaching at Ahmadu Bello University, Nigeria while studying for postgraduate qualifications. After graduating from Adelaide in 1998, I worked in South Africa, first as a Postdoctoral Fellow at the Universities of Natal (now KwaZulu-Natal) and Pretoria, then as Senior Lecturer at the Technikon Free State (now Central University of Technology), and the University of KwaZulu-Natal (UKZN).

My research interests centre on the nutrition and digestive physiology of farm animals. I developed the necessary protocols to investigate the activities of pancreatic, intestinal and microbial enzymes, in response to changes in age and dietary regimen at UKZN and the University of Pretoria. The techniques that are used for these studies include biochemistry, cell kinetics, cytochemistry and immunohistochemistry. Most of my research focuses on the digestive physiology of poultry. Most recently, I investigated the digestive physiology of broiler breeder pullets and key local breeds of chickens found in South Africa.  My long-term research plans are to investigate avenues for reducing environmental pollution using nutritional intervention, and to develop physiological techniques as aid to poultry selection.  I have published about 55 peer-reviewed articles in journals and made presentations at many international conferences.  Prior to departure from South Africa, I was rated C2, which is assigned to researchers that are recognised by their peers as established in research.

I serve on the editorial boards of the Journal of the Science of Food & Agriculture (http://www3.interscience.wiley.com/cgi-bin/jhome/1294) and the International Journal of Poultry Science (http://www.pjbs.org/ijps/ijps.htm); The Open Food Science Journal (http://www.bentham.org/open/tofsj/), Indian Journal of Poultry Science, Bulletin on Animal Production and Health in Africa (http://www.ajol.info/journal_index.php?jid=227&tran=0&ab=bahpa) and the South African Journal of Animal Science (http://www.sasas.co.za), and review for a number of other journals.
