Main topic

Gall wasps are insects capable of inducing structures called galls providing shelter against antagonists and varying climatic conditions, as well as food for their progeny, thereby increasing their survival. They do it by manipulating their host plant gene. The genetic basis of the ability to induce or form galls, on different plant species and organs, remains largely unknown and poorly studied. I used a mix of evolutionary approach to tackle this problem : population genomics, phylogenomics and transcriptomics.

Former/side topics

Cheese is a fermented food product that is the result of the transformation of milk by a
variety of microorganisms. Two Penicillium fungi are used for the maturation of cheese :
* Penicillium roqueforti, the blue mould, used for producing blue cheese
* Penicillium camemberti, the white mold, used for the production of Camembert-type
We use comparative genomics to understand the genetic basis of parallel adaptation of these two species to cheese.
We also use population genomics to unravel the history of domestication of Penicillium roqueforti.
