I use a variety of approaches (bioinformatics, cytogenetics, mathematical modelling…), mainly to try and get a better understanding of the ultimate causes responsible for transitions among different sex determination systems, and to study the origin as well as the structural and sequence evolution of newly emerged sex chromosomes. I’m also interested in other research topics, such as genomic conflicts (in particular sex chromosome drive). My current project aims at analysing the origin and evolution of the multiple sex chromosomes and neo-sex chromosomes of the African pygmy mouse Mus minutoides, using a combination of genomic and transcriptomic data.
