Current research activities

My research activities are focused on comparative and integrative genomics. They combine the study of biological systems and data science with the development of strategies and tools necessary to extract knowledge from massive data. They are largely based on the exploitation of the evolutionary message provided by the comparison of homologous sequences.

Development of open resources for comparative genomics

We develop the OrthoInspector program for predicting orthology relationships between genes. The associated OrthoInspector website provides orthology relationships for more than 4000 species and offers tools for data exploration and visualization, allowing phylogenetic profiling or evolutionary characterization of genes associated with a function, a process or a cellular component. We are also working on the detection of differential conservations between homologous protein sequences. The PROBE program allows the automated analysis of a protein family to identify and visualize conserved blocks corresponding to domains or motifs still unknown that may have a structural and/or functional role. BLUR (BLast Unexpected Ranking) allows to compare the proteomes of 2 taxa in order to identify the divergences between species, whether they result from the loss/gain of proteins, blocks or the divergence of a homologous region.

Genotype/phenotype relationships

EvolutionWe exploit omics data to characterize genotype/phenotype relationships, in particular in the context of the study of ciliopathies which represent a large group of diseases related to dysgenesis or dysfunction of the cilium(s). Phylogenetic profiling (presence/absence of orthologs) of human genes in a wide range of eukaryotic species has allowed us to identify new ciliary genes in collaboration with the Medical Genetics Laboratory of Strasbourg. We have also defined a specific evolutionary signature of multiciliation and developed an original approach integrating comparative genomics and functional genomics to identify new genes involved in multiciliation.

Evolution and biodiversity

• Genome evolution in Decapoda

The genomes of decapods show considerable variation in size. We are working on sequencing the giant genome of the noble crayfish Astacus astacus(17 Gb), a European species currently threatened by crayfish plague. The genome coupled with complementary omics data will be used to identify the molecular basis of immunity in crayfish and to understand the differences in resistance to crayfish plague observed between populations in order to eventually allow the reintroduction of resistant individuals. This genome will also be compared to other available decapod genomes to understand the evolution of chromosome organization, gene repertoires and repeated elements. This project is carried out in collaboration with the LOEWE Centre for Translational Biodiversity Genomics in Frankfurt and is funded by ANR/DFG.

• Genomic exploration of Myriapod diversity

We are working on the annotation and comparison of 20 Myriapod genomes. Myriapods (millipedes and centipedes) are essential invertebrates for soil biodiversity but are still largely unknown at the genomic level. The comparative analysis of these genomes should allow us to learn more about metamerization, the ancestral genome of arthropods and the adaptation of species to more or less anthropized environments. This study is part of the MetaInvert collaborative project initiated by LOEWE Centre for Translational Biodiversity Genomics that aims to characterize the genomes of soil invertebrates and to establish correlations between genomic and ecological traits. The genomes will then serve as a reference for the identification and quantification of individuals using metagenomics approaches.
