Sandra Moreau, IEHC

Sandra Moreau

After obtaining a Master in Plant Biotechnology from Denis Diderot University - Paris 7 in 2001, Sandra worked on the development of the seed at the INRA Versailles and then on the study of a disease in rapeseed at INRA Evry. She was then recruited by the CNRS in 2004 at the LIPM to work on nodular development under the supervision of Pascal Gamas, in the Endosymbiotic infection and nodular development team. She has participated in the genomics, transcriptomics and genetic analysis programs of transcriptional regulators involved in the development of the nodule in Medicago truncatula. Since 2019, she has joined Aurélien Carlier's team to work on the leaf symbiosis in Dioscorea sansibarensis.


Tessa Acar, PHD student

Tessa Acar

Tessa graduated from Ghent University with a Master's degree in 2017 and started her PhD in the Microbiology lab at Ghent University. After two years, she moved with the lab of Aurélien Carlier to the LIPM at INRAE Auzeville. During her PhD, she’s investigating the life cycle and transmission of vertically-transmitted bacterial symbionts of plants using in vitro cultures and microscopy techniques.


Bram Danneels, PHD student

Bram Danneels

Bram graduated from Ghent University in 2017 with a Master's degree in Bioinformatics. Currently, he is applying bioinformatics and (meta)genomics techniques to plant-bacteria associations, in particular the Dioscorea/Orrella leaf nodule symbiosis. Together with the lab, he moved from Belgium to France in September 2019 to finish his PhD.


Sarah Ranty-Roby, PHD student

Sarah Ranty-Roby

Sarah Ranty-Roby first obtained an ecology bachelor degree at University Paul Sabatier (Toulouse, France) as she was first attracted by ecology and biological questions related to this discipline. During this degree, she made several internships in three domains: plant ecology, animal behaviour and molecular biology. She also developed a specific interest for plant physiology and she continued her cursus with a plant physiology master degree (ADAM) at University Paul Sabatier (Toulouse, France). During this master degree, she had the chance to work in plant-nematode and plant-insect interactions. Her master project was focused hormonal salicylic/jasmonic acid crosstalk in response to Pieris brassicae egg extract and larvae wounding. She developed this project at Lausanne University (Switzerland). Today, Sarah Ranty-Roby join the LIPM as a PhD student in the “Symbiotic association in the phyllosphere” team under the direction of Aurelien Carlier. Her PhD project deals with the molecular determinants implicated in the establishment and maintenance of specific plant-microbe interactions in the leaf using the interaction Orrella dioscoreae-Dioscorea sansibarensis.
