Bernard obtained a BSc in Biomedical Science and Technology in 2008 and MSc in Medical Entomology and Vector Science in 2012, both from Maseno University, Kenya. He worked with the Kenya Medical Research Institute and US Centres for Disease Control and Prevention (KEMRI/CDC) public health collaborations from 2012 to 2015 in different entomological projects. He joined Abt Associates Inc, as entomology consultant for the PMI funded African Indoor Residual Spraying (AIRS) programme in 2016 and as the programme technical manager in 2017.
Bernard joined LSTM in April 2015 as a PhD student.
Evaluation of community based vector surveillance system in a region with low mosquito density
Sustained use of LLINs and application of IRS have been demonstrated to have impact on mosquito bionomics. It is envisioned that with increased application of existing interventions and introduction of new ones, vector numbers would reduce markedly and distribution become patchy, that it would be difficult to collect sufficient mosquitoes for entomological evaluations. The current study evaluates effectiveness of an unsupervised community based mosquito surveillance strategy against the traditional entomological surveillance system usually by supervised, trained entomology technicians. The study area is organized into 18 clusters, each with 60 randomized compounds. In each cluster, a member of the community is provided with a set of light traps and battery charging system. Three houses are sampled daily in each cluster. Mosquito samples are stored in ethanol in the field and collected every two weeks for laboratory analysis.
Evaluation of effectiveness of IRS with pirimiphos methyl in region with widespread pyrethroid resistance in western Kenya
The Kenya National Malaria Control Programme in collaboration with other partners, plan to implement IRS with pirimiphos methyl in a region with widespread pyrethroid resistance in Anopheles mosquitoes. To evaluates effectiveness of the IRS programme in vector control and insecticide resistance management, the current study conducts vector surveillance to monitor mosquito numbers, species composition, behaviour, and insecticide resistance before and after IRS.
