Research interests

My research interest is to understand the molecular mechanisms and evolutionary forces that generate and maintain structural variants in plant genomes, and to what extent they contribute to plant adaptation. Using maize as a model species, I am particularly interested in Presence/Absence variants and how they shape maize pan-genome structure. For this, I use and develop bioinformatics approaches to analyze massive parallel sequencing data and genome sequence assemblies. My research takes place within the French investment for the future Amaizing program, in which I lead WP2 and Task 3.1.

For a part of my time, I lead the Biological Sequence Analysis facility group that offers support in bioinformatics to other GQE groups.

In the past years (2008-2016), I was the head of the GQE Bioinformatics facility (ABI).

This facility had in charge management of local high-performance compute resources, data management, database development and development of data analysis and visualization software for genetics and genomics. The group included up to six permanent staff as well as several students and non-permanent engineers.

There, I initiated and led the development of the software BioMercator (ANR program ANR-08-GENM-004) and the PROTICdb database (ANR PROTICws).

I have been involved in massive parallel sequence data analysis since 2010, and decided to start my own research program in this area in 2016 and joined the DyGAP team. To focus my activities in biological sequence analyses, I kept the lead of biological sequence data management and analysis and passed over database management, software development and management of shared computer resources, thus leading to a split of the ABI facility into 3 groups.
