Hi, my name is Christiaan Kooyman. I was born in Hengelo, the Netherlands, where I studied ecology at the Agricultural University of Wageningen (nowadays Wageningen University and Research Centre). After my Master's graduation I moved to Africa, where I have worked ever since in many countries (countries of residence: Nigeria, Kenya, Sudan, Niger, Benin, Senegal and Morocco). Most of my jobs involved aspects of entomology. Since 1996, I consider myself an entomopathologist (insect pathologist). My current job is technical advisor in the R&D department of the biopesticide and biofertilizer company ÉLÉPHANT VERT, based in Meknès, Morocco. I am acting head of the bio-insecticide section, where we develop products containing entomopathogenic fungi.
