Research Interests
I am interested in how behaviour and nutrition are shaped by social and sexual interactions in insects. During my PhD, I investigated how the socio-sexual environment (such as mating rate, sexual harassment and long-term diet) impacts behaviour, reproduction and diet choice, using the fruit fly model system Drosophila melanogaster. During my post-doc at JGU Mainz with Prof. Dr. Susanne Foitzik I will investigate how social interactions impact behaviour, gene expression and nutrition in a new system, by way of the ant social parasite Temnothorax americanus, and its exploited ant host Temnothorax longispinosus. Specifically, I will research: 1) genomic interactions between parasite-specific and host-specific genes that could determine success of parasitism or host defence; 2) changes in gene expression patterns that trigger the seasonal behavioural switches necessary for parasites to raid host nests for new workers, and; 3) how networks of nutrient sharing via social fluids may be used to manipulate workers in socially-parasitised colonies.
