Maëlle did her PhD in the Reproduction and Developmental Biology Laboratory at the National Institute of Agronomic Research (INRA, Jouy-en-josas, France). She studied how genes involved in sex differentiation are expressed. Her post-doctoral research focussed on epigenetic mechanisms in general and on genomic imprinting in particular. Now she works in Robert Feil’s lab looking at special enzymes called histone methyltransferases that move chemical markers between histone proteins around which DNA is intimately wound. She's interested in the hotspots that affect heritable silencing of certain genes.
