Ecology of Multitrophic Interactions &  Biomimetism
Géraldine Dubreuil recently obtained a permanent position as a Maître de Conférences at the University F-Rabelais in Tours. She joined the IRBI in September 2012 and is now working with David Giron on the functional ecology of the plant-insect-endosymbiont interactions. She previously mainly worked on Host-Pathogen systems including a plant-nematode and a plant-aphid system. Her background in Functional Genomics (including Transcriptomic analysis, RNAi, Virus-Induced-Gene-Silencing, Proteomics…) and Biochemistry will be highly valuable in our understanding of the molecular dialogue involved in the interaction between the leafminer P. blancardella and its host-plant and the pivotal role played by insect endosymbiotic bacteria.
