Research interests

I have a strong interest in the evolution of life history traits, mechanisms underlying castes differentiation and more broadly societal organizations in social insects. The complexity of these societies makes them interesting to explore from an evolutionary perspective and I am enthusiastic at the idea to investigate such research questions using behaviour, genetics and epigenetics, which I find fascinating.

PhD project

Most living organisms are facing a trade-off between fecundity and longevity regarding their resource allocations. However, in social insects, this trade-off is reversed so that the queen, which is the most fertile individual, is also the longest lived while the workers are non-reproductive individuals and live shorter. The aim of my project is to explore the underlying molecular basis of this positive association using the ant Temnothorax rugatulus as study model. Using experimental manipulations, behavioral observations and gene expression analyses I will investigate (i) the regulation and connectivity of candidate genes in gene regulatory pathways and (ii) epigenetic mechanisms regulating expression in these pathways as well as (iii) the influence of diet and particularly protein content on ant fecundity and longevity and finally (iv) the potential improved immunocompetence in queens following an induced increased fecundity.
