Introduction
I am very interested in social insect societies and associated features such as their fascinating caste system, complex eusociality, or the longevity-fecundity reversed trade-off they display. I am investigating related questions using experimental manipulations, laboratory methods, behavioral observations, and bioinformatics.

Organisms that can detect parasites may have a greater likelihood of avoiding exposure to them. We would expect hosts that share an evolutionary history with a parasite to be more likely to detect and avoid it compared to novel hosts. Nosema ceranae is a gut parasite of the Asian honey bee, Apis cerana , that has relatively recently been detected i...

Background In insect societies, queens monopolize reproduction while workers perform tasks such as brood care or foraging. Queen loss leads to ovary development and lifespan extension in workers of many ant species. However, the underlying molecular mechanisms of this phenotypic plasticity remain unclear. Recent studies highlight the importance of...

In insect societies, the queen monopolizes reproduction while workers perform tasks such as brood care or foraging. Queen loss leads to ovary development and lifespan extension in workers from many ants. However, the underlying molecular mechanisms of this phenotypic plasticity remain unclear. Recent studies highlight the importance of epigenetics...

Alternative reproductive strategies are often associated with distinct morphological phenotypes. Some ant species display two queen morphs: larger queens (macrogynes) conduct mating flights followed by independent colony foundation, whereas smaller queens (microgynes) are readopted by their mother colony. In some cases, microgynes can evolve into s...

In insect societies, the presence of reproductives or eggs has been shown to shape several biological traits in the colony members. Social interactions are one of these traits that involve modification of the communication system of the entire colony. Many studies described the role of chemical compounds and dominance behaviors in the presence of r...

Using experimental manipulations, laboratory methods, behavioral observations, and bioinformatics, I am investigating the (epi)genetic basis of fecundity and longevity, the influence of protein content in diet, and the link between fecundity and immunity, in the ant Temnothorax rugatulus.
