Carreer Path

  • Initially trained in computer science (ENSEIRB engineering school, Bordeaux), I did my phD (2002-2006) about the automatic reliable identification of gene structures in eukaryotic genomes (Exogean) under the supervision of Hugues Roest Crollius (Institut de Biology de l’Ecole Normale Supérieure, Paris) and Franck Delaplace (Université d’Evry).
  • I then moved (2006-2015) to the Centre for Genomic Regulation (CRG) in Barcelona, Spain, to work on the international ENCyclopedia Of DNA Element (ENCODE) project as a postdoctoral researcher. Within the ENCODE transcriptomic sub-project led by Thomas Gingeras and Roderic Guigó, I coordinated the analyses of genome-wide transcriptomic data (RNA-seq, CAGE, RNA-PET) produced for the first time in a very exhaustive way (many cell lines, RNA fractions and cell compartments). I also coordinated the mouseENCODE transcriptomic analysis efforts and developped the ChimPipe program to identify all types of chimeric RNAs from RNA-seq data.
  • In 2015,  I moved back to France (Toulouse, Agreenskills+ fellowship) to coordinate the bioinformatics analyses of the INRA French Animal Genome ENCODE project (FR-AgENCODE, RNA-seq, ATAC-seq and HiC data from 4 species) together with Sylvain Foissac.
  • I am now interested in the robust automatic identification of enhancer-gene relationships in the genomes and how it can help understanding complex human genetic diseases.​ In 2019 I was recruited as an INSERM permanent researcher (CRCN) to lead this project at the Digestive Health Research Institute (IRSD), Toulouse.

INTEGRATIVE ANALYSIS OF HIGH-THROUGHPUT FUNCTIONAL GENOMIC DATA
ALGORITHM AND PROGRAMMING

RESEARCH/PROJECT
The robust automatic identification of regulatory relationships in the genomes, and how it can help understanding complex genetic diseases.
​My project is organized in two parts:
  • the robust automatic identification of regulatory relationships genome-wide (focusing first on enhancer-gene relationships). After an evaluation of state-of-the-art methods on several gold-standard datasets, I will define the best approach that also relies in a minimal set of assays
  • the focus on complex genetic diseases studied in the lab such as hemochromatosis and Parkinson’s disease: after identifying important regulatory relationships in cell types related to these diseases, I will integrate them with genetic data to identify new variants, regulators, genes and pathways involved in the diseases.
