I have extensive experience in basic and applied research on disease vectors and infectious disease pathogens of military importance. For the last 10 years as a research entomologist, I have been involved in research, development and evaluation of products for protecting the War-fighter from vector- borne diseases and nuisance biting insects. I spearheaded the development and fielding of field deployable vector pathogen Immunochromatographic lateral assays for Rift valley fever virus, Dengue virus, and Leishmania major. These assays now form part of the Army Preventive Medicine Medical Equipment sets. In addition, I have collaborated with host nation partners within AFRICOM and Pacific Theaters, foreign militaries, inter agency partners, private industry, and regional academic research institutions to train, conduct research and strengthen relationships needed to address arthropod-borne disease threats. I have managed more than 60 research projects with an annual budget exceeding $4.6 million, resulting in multiple publications in peer reviewed journals. I’m a recipient of the German Academic Exchange Service Grant (DAAD); Canadian Commonwealth Scholarship and fellowship; World Bank, Agricultural Research Fund; University of Guelph, Environmental Science Dean’s award; and University of Jos, Nigeria Graduate Student Dean’s award. I'm a member of the Military Acquisition Corp and also Level II Science and Technology Manager certification. As a military service member, I have received a number of awards to include Meritorious Service Ribbon- Two Oak leaf clusters, Army Commendation Medal- single oak leave cluster, Iraqi Campaign Medal and Army Achievement Medal.
