Current topic of research :

Adaptation of Penicillium molds to fermented food

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 cheese.

Dry-cured meat is also a fermented food product that make use of two Penicillium species to give some protection against spoiling agents and produce flavours:

  • Penicillium nalgiovense, is an industrial species

We use comparative genomics to understand the genetic basis of parallel adaptation of these four species to fermented food products.

We also use population genomics to unravel the history of domestication of Penicillium roqueforti (https://www.biorxiv.org/content/10.1101/451773v1).

The genetic basis of gall induction by gall wasps (Hymenoptera:Cynipidae)

Gall wasps are little insects that are capable of inducing the formation of differentiated tissue by their host plants.

Hence, the gall gives a shelter and food for the larvae of the wasp.

I was recently awarded a young researcher 4-year grant (ANR JCJC) to start working on the genetic basis of gall induction
