2014-present : Postdoctoral Research Associate with Prof John Carr. My main project  focused on understanding vector behaviour and how it can be utilised to reduce the spread of viral disease on common bean crops in Kenya. Our collaborators are based in BeCA-ILRI Hub in Kenya and Rothamsted Research, UK. 

2010-2014 : PhD in Virology and Molecular Plant Pathology, University of Cambridge. Thesis title on Cucumber mosaic virus modifies plant-aphid interactions with Prof John Carr. 

2009-2010 : MSc in Environmental Technology, Imperial College London. Dissertation topic on above ground carbon storage in tropical peatlands soil in Borneo, Indonesia with Dr Jeremy Woods and Dr Mairi Black.  

2005-2008 : BSc in Biology, Imperial College London. Dissertation topic on glucosinolates and how they affect aphid performance with Dr Glen Powell and Dr John Rossiter. 

Research Interests

My main research interest is to investigate how plant viruses are able to modify vector behaviour, and in turn how these may facilitate onward transmission of the virus. In addition, I am also actively involved to organise the annual molecular laboratory training workshop for African agricultural research scientists - with JR Biotek Foundation and the Department of Plant Sciences at Cambridge.
