Sarah is a vector ecologist specializing in the chemical ecology and control of Anopheles mosquitoes. This includes devising methods to attract mosquitoes in order to monitor their numbers for evaluation of control programmes and to trap and kill mosquitoes. She also works on new and existing methods of repelling mosquitoes to protect individuals, households and communities. All of these projects involve rigorous field evaluation of methods to reduce mosquito-borne disease transmission. The research also has a strong social science component to ensure that technologies developed are compatible with the needs and wishes of the communities that use them. Much of Sarah’s work involves developing appropriate technologies and methodologies for the Eastern African setting. Sarah is a key member of ARCTEC Expert Team and is based full time at Ifakara Health Institute in Tanzania.
