Background and other Interests:

I obtained my BSc (Hons) from the University of Maiduguri, in Nigeria (http://www.unimaid.edu.ng); MSc from Aberdeen, Scotland  (http://www.abdn.ac.uk), and PhD from The University of Adelaide, Australia (http://www.adelaide.edu.au ).  More recently (2006), I completed studies for the Graduate Certificate in Higher Education at the University of New England, Australia.  I have previously worked at Ahmadu Bello University, Nigeria (1987-1999); University of KwaZulu-Natal, South Africa (1999-2001; 2003-2004);  University of Pretoria, South Africa (2002) and for a short period at the Technikon Free State (now Central University of Technology, 2002).

My research interests centre on the nutrition and digestive physiology of farm animals, particularly poultry, using biochemistry, cell kinetics, cytochemistry and immunohistochemistry, among other techniques.  More recently, I have been involved in research into alternatives to in-feed antibiotics in poultry diets and the potential of various low-cost alternative feed ingredients for poultry.  I have published one scientific book, one general interest book, four book chapters, about 72 peer-reviewed articles in journals, and made presentations at many international conferences.  To date, I have graduated nine PhD, six Masters and two Honours students.

I serve on the editorial boards of a number of scientific journals, including the Journal of the Science of Food & Agriculture (http://www3.interscience.wiley.com/cgi-bin/jhome/1294); Animals (http://www.mdpi.com/journal/animals/); Asian Journal of Poultry Science (http://scialert.net/jindex.php?issn=1819-3609); International Journal of Poultry Science (http://www.pjbs.org/ijps/ijps.htm); South African Journal of Animal Science (http://www.sasas.co.za), and Indian Journal of Poultry Science (http://www.indianjournals.com/ijor.aspx?target=ijor:ijps&type=home), and the and review for a number of other journals.
