My research concerns the study of the role of transposable elements (TEs) in the evolution of eukaryotic genomes using comparative genomics and bioinformatics approaches in different organisms. Since several years, I have developed expertise in the identification of TEs in sequenced genomes, the study of their effects on neighboring genes, but also in the evolutionary analysis of TE sequences.

 

Projects

• Detection of TE copies in whole genome sequences to analyze their dynamics and evolution. For this, we have developed several programs:

  • Genome-wide statistic method to detect horizontally transferred sequences without any a priori  (Modolo et al. 2014) available here.
  • Tool to parse RepeatMasker output file in order to obtain detailed information concerning the TE content in a genome at the family level (Bailly-Bechet et al. 2014) available at One-code-to-find-them-all.
  •  Tool to performe transcriptomic analysis of TEs  (Lerat et al. 2017) available here.
  •  In development: tool to simulate a distribution of polymorphic TE insertions.

• Study of the link between TE insertions, epigenetic modifications and gene expression under various conditions (for example: normal cells vs tumor) in mammals and Drosophila.
•  Influence of TEs on the evolution of duplicated genes .
• Participation in the development of a reference for the annotation of TEs in genomes with several international researchers (Hoen et al. 2015).
