Dr. Kashe holds a PhD in Weed Science from University of New England, Armidale , Australia. He joined Okavango Research Institute (ORI) as a Research Scholar in April 2013.  Before that he worked as Principal Researcher in Weed Science at Department of Agricultural Research, Ministry of Agriculture. His research then had been in ecology and adaptations of crop weeds, mainly working with farmers on management and control of weeds in their farms.  Since joining ORI, his research now includes: (i) dry land vegetation including vegetation inventory and  impacts of invasive plant species, (ii) monitoring the impacts of  land-use change on plant populations and communities (iii) supervision of the development and maintenance of  the ORI herbarium. Dr Kashe has worked on several international projects:  Wild plant post-genomic project-analysis of  genes of wild watermelons responsible for resistance to drought stress and high light intensity or high temperature,  management of weed parthenium in eastern and southern Africa using integrated, cultural and biological measures and building alliances for effective striga research and control.  Through these international collaborations , he visited countries such as Japan, Ethiopia and Burkina Faso.
