PhD student : State-dependent regulation of odour-mediated behaviour in the mosquito Aedes aegypti

To improve mosquito vector control we need a better understanding of the mechanisms underlying the state-dependent modulation of odour-mediated and host-seeking behaviour of Aedes aegypti. This mosquito species is the principle vector of globally important arboviruses such as dengue, yellow-fever, Chikungunya and more recently Zika.

My PhD project aims to investigate the chemosensory gene expression in the primary olfactory tissue, the antennae and to identify olfactory receptor genes of interest that are regulated in response to different physiological states. I study the modulation of gene expression according to maturation of both sexual and host-seeking competence, and to infection by both dengue and Zika viruses. Regulated odorant receptors will be subsequently functionally characterised.

My project combine both transcriptome and behavioural analysis as well as several skills belonging to the field of chemical ecology.

My PhD will hopefully expand the understanding of chemosensory gene family regulation and how odorant receptors influence olfactory driven and state-dependent behaviours in Aedes aegypti.
