Presentation

Research

My research interest is centered on cytogenomics :

 

  • Comparative studies of genomic structure between species, with a special focus on the distribution or repeated elements,

 

  • Chromosome evolution, identification of chromosomal rearrangements and breakpoints,

 

  • Consequences of chromosome evolution on speciation.

 

This research is conducted on different biological models, including mammals, bird, butterflies and moths, more particularly on species having a very derived genomic organization among their groups, with the goal to decipher the evolutive forces underlying this reorganization.
