Projets actuels ou récents de recherche auxquels je participe:

  • Au sein du projet mené par Didier Casane sur l’étude de la démographie d’Astyanax mexicanus (poisson cavernicole du Mexique), j’identifie chaque poisson par l’analyse de locus microsatellites, et les compare aux génotypes obtenus au cours des différentes missions pour évaluer le taux de recapture afin de déterminer la taille des populations (publication n°9).
  • J’ai participé à l’Etude de la voie de signalisation du métabolisme de l’acide rétinoïque et du patron d’expression des gènes impliqués, chez la petite roussette (Scyliorhinus canicula). Projet porté par Véronique Borday-Birraux (publication n°11)
  • Je collabore avec Laure Kaiser-Arnauld, Florence Mougel et Samuel Gornard du pôle Evolution et Ecologie dans un projet qui consiste à étudier la réponse immunitaire d’une chenille Sesamia nonagrioides, responsable de ravages sur le maïs, au parasitisme par la guêpe Cotesia typhae.
