Introduction
I am a veterinary surgeon whose interest lie in anatomical/pathological applications in disease investigations. Although I have done a lot of work in abattoir meat condemnations, I have also done a lot of work in epidemio-survaillance of diseases of economic and zoonotic importance and several aspects of animal production in Rwanda, South Africa and Namibia
