At Eastern Since 2005
I have been teaching in the Department of Biology at Eastern University since August 2005. I began my scientific career as a Plant Protection Research Officer in Nematology in the Ministry of Agriculture in Harare, Zimbabwe. This was followed by a teaching and research career in Nematology, Parasitology and Invertebrate Zoology in the Dept. of Biological Sciences at the University of Zimbabwe (UZ). For five years during this period, in addition to my normal teaching duties, I was also Chair of the Department of Biological Sciences. In addition, I was also a UZ team leader for the joint UZ/Nihon University of Japan research grant for the advancement of molecular technology in vegetable production for the small scale farmers of Zimbabwe, UZ coordinator of a collaborative UZ/IUP exchange link agreement and a fish parasite research collaborator with the UZ/Belgian Flemish Universities Fisheries project.
Prior to my joining Eastern University in fall of 2005, I spent three and half years at Indiana University of Pennsylvania as a Visiting Professor and later as a temporary faculty in the Dept. of Biology. Inspired by the plight of small holder farmers in Zimbabwe in their quest to increase vegetable food production and by my overall desire to be a practical, environmentally conscious scientist in the fight to alleviate hunger among the less privileged, my research interest has remained focused on an ecologically sustainable integrated nematode control strategy. Plant-parasitic nematodes particularly rook - knot nematodes (Meloidogyne sp.,) are a severe constraint on agricultural vegetable production.

Why I Teach at Eastern:
Eastern University community (administration, faculty, staff and students) provides a stable and congenial Christian environment for both excellence in learning, teaching and research. This environment is both intellectually inspiring and spiritually uplifting and one which I continue to benefit from immensely in my lifelong endeavor to serve God and humanity through science and technology.
My current research involves the integrative use of bacteria (Pasteuria penetrans), fungi (Paecilomyces lilacinus), soil solarization and organic amendments in managing root-knot nematodes (Meloidogyne sp.) on vegetable crops. This research program is centered on laboratory, greenhouse and field biological control studies of plant – parasitic nematodes. The overall goal of my research program is to develop a cheap, low technology, environmentally sustainable nematode management strategy that is applicable, appropriate and relevant to subsistent and poor farmers in developing countries.
As Christians, we have been commissioned to use our creative capacities to glorify God in service to others and in the management of His creation. As further evidence of our love for our neighbors, De Witt (1994) suggested that science scholars of Christian faith should “serve the poor by using Science and Technology”.
