(Hons) - 2000 (Agriculture). A. Positions, honours and research support 1. Positions and Employment 2005 – Current: Senior Research Scientist (Plant Pathology) - working mainly on the epidemiology of the cocoa swollen shoot virus disease. Leader of several field and guaze house research projects on mild strain cross protection, screening of cocoa progenies for resistance/tolerance against CSSV and use of intercropping as CSSVD management strategy, search for alternative hosts and vectors of CSSV. 2011 – 2015: Research Assistant (Plant Pathology) North Dakota State University – my work focused mainly on managing the potato mop-top virus disease through cultivar selection and use of differing soil moisture regimes. 2000- 2001 – Research/Teaching Assistant (Crop Science Department) Kwame Nkrumah University of Science and Technology, Kumasi – Provided assistance in supervising laboratory classes, design and implementation of student project work, marking of exams scripts. 2. Other Experience and Professional Memberships Member of Ghana Science Association (GSA); member of American Phytopathological Society 3. Honours, awards and research support. Award: Phi Kappa Phi Scholar; DFID Commonwealth Shared Scholarship Scheme Award; CIRAD scholarship for work on understanding the CSSV species complex.
