My PhD project is part of the GenoScent project, an MRC-funded project that aims to investigate the genetic basis of attractiveness to mosquitoes, both in the UK and in a natural host-vector-parasite system in The Gambia. The study will provide insight into the mechanisms that can affect our body odour, and make people more or less attractive to mosquitoes. By collecting body odour from identical and non-identical twins in the UK and The Gambia, we will test the relative attractiveness of twins to the major vector of malaria, Anopheles mosquitoes, in behavioural experiments as well as investigate their odour profiles. My PhD is focused on the skin microbiome of these participants. I will associate the skin microbiome with the body odour and attractiveness to mosquitoes. Understanding the role of the microbiome in how humans produce natural attractants and repellents could be used to develop novel vector control tools in the future.
