Pauline Blanquet, PhD student CJS INRA


After studying microbiology and agrobiosciences at the Paul Sabatier University (Toulouse) from 2007 to 2010, Pauline obtained a Master’s degree in Plant Sciences at the Paul Sabatier University (Toulouse) in 2012. She joined Claude Bruand‘s team in January 2012 and then obtained an INRA CJS (contrat jeune scientifique) PhD grant in July 2012. She studies the action modes and controls of nitric oxide level in nodule senescence process during the Sinorhizobium meliloti-Medicago truncatula symbiosis. Pauline is now working in a private company.

Pierre Dupuy, PhD student CJS INRA

Pierre DUPUY

Pierre joined the group in 2012 and obtained a Master degree in Microbiology at the Paul Sabatier University of Toulouse in June 2013. He started his PhD in October 2013 supported by a three years  contract with INRA (Contrat jeune scientifique), under the supervision of Claude Bruand. His PhD project consists in the functional characterization of the general stress response in the nitrogen-fixing symbiotic bacterium Sinorhizobium meliloti. Pierre is now working as a post doc in New York, USA.

Eugénia Cernov, Master Student

IMG_1023 122 150

Eugénia Cernov joined our group in January 2017 to prepare a Master 2 thesis. She studied microbiology at the University of Toulouse. Eugénia worked on a collaborative project shared by the Bruand and the Gamas Groups.

Gaofei Jiang, Post doc

Gaofei J 122 150

Gaofei first postdoc was started beginning 2017 in Group of Claude Bruand at LIPM where Gaofei contributed to understand the tradeoffs involved during rhizobium-legume interactions.​

Alexandre Le-Scornet, Engineer

Le-Scornet Alexandre

Alexandre obtained his Master degree in Microbiology at the Paul Sabatier University of Toulouse in June 2016 after his graduation internship in the team. This Internship aimed at understanding the synthesis and the role of nitric oxide during the symbiosis between S. meliloti and the model legume M. truncatula. He was then hired to study the latter stage of the rhizobium-legume symbiosis. He is now preparing a PhD thesis in the LMGM in Toulouse.

Antoine Rémy, Engineer

Antoine Rémi

Antoine obtained in 2015 a Master Degree in Biochemistry and Biotechnology from the University Paul Sabatier in Toulouse. In 2016, he joined group of Claude Bruand in the LIPM to work on the Staypink ANR project « Mecanisms controlling the transition between nitrogen fixation and senescence in legume symbiotic nodules”.

Adrien joined the Bruand's group to prepare his Master thesis (Master 2 ‘Sciences du Végétal’ (Paris-Saclay University)). 

Claire Benezech, PhD Student

Benezech 150 pi de haut

Claire joined the group in 2016 to study the latter stages of the symbiotic process. She successfully completed her PhD defense on September 27th, 2019.

Anne-Claire Cazalé, Ingénieur de Recherches INRA

CAZALE Anne-Claire

Anne-Claire has studied signalisation (reactive oxygen species production and protein kinases) in plants in response to abiotic stress during her PhD at the ISV (CNRS, Gif-sur-Yvette, France) and during her post-doc at the MPIZ (Koeln, Germany). She analyzed the heavy metal tolerance during two post-docs at the Leibniz-IPB (Halle/Saale, Germany) and at CEA Cadarache (France). At CEA Cadarache, she also studied the regulation of the alternative photosynthetic electron transfer pathway. She joined the LIPM in 2007 to contribute to the characterization of the type III effectors from Ralstoniasolanacearum in the team of Stéphane Genin. From 2015 to 2020, she joined the our team to participate in the elucidation of the roles of nitric oxide (NO) in the Medicago truncatula-Sinorhizobium meliloti symbiotic interaction. Especially, Anne-Claire studied the protein post-translational modifications induced by NO. From 2021, Anne-Claire joined Delphine Capela's group to work on other aspects of rhizobia-legumes symbiosis.

Maëva Doudement, PhD student

M doudement 150x111

Maëva Doudement performed a master thesis in Aix Marseille University in the group of Emanuele Biondi. She joined the Bruand's group to work on the rhizobium-legume symbiosis in the frame of the Trolesinfidels project.

Guillaume Dubrulle, ATER Université Paul Sabatier


After a PhD at the University Bretagne Occidentale. Guillaume joined the RLE group to work on the Trolesinfidels project.
