My research is focused on understanding the regulation of the expression of polygenic traits at the molecular level, and their evolution. I recently received a Marie Skłodowska Curie Individual Fellowship to study polygenic adaptation targeting gene expression regulation using eQTL Networks.

Polygenic adaptation, in which small changes in allele frequencies co-occur at multiple variants, has been proposed to be a major adaptive mechanism for polygenic traits. Because 90% of genetic variants associated to polygenic traits are located in non-coding, regulatroy regions, I’m interested into studying the extent to which polygenic selection targets regulatory regions of the human genome. I propose to combine network biology and population genetics methods in order to develop a new approach to detect signatures of polygenic adaptation in regulatory regions.

Role of Enhancers in Maize Leaf Development Gene Regulatory Networks

This project aims at studying the role of transposable elements in the enhancer-mediated tissue-specific regulation of gene expression in maize tissues. I want to understand how transposable elements inserted in the neighborhood of genes have been shaping the tissue-specific gene regulatory networks. To this end, I use maize as a model, and I combine approaches from comparative genomics, systems biology and computational biology.

Previous projects

During my first postdoc, I investigated the genetic bases of the regulation of the expression of polygenic traits, using system biology approaches based on bipartite network representation. I notably characterized the regulatory role of germinal mutations increasing the risk to develop cancers.

PhD thesis - Genetic and epigenetic bases of human populations adaptation to the environment.

I did my PhD in population genomics and epigenomics. I studied the impact of the global environment on the genetic and epigenetic diversity of human populations. I investigated the role of a particular type of positive selection, selective sweeps, in shaping the human genome diversity. I also assessed the relative impact of genetic and environmental factors on the variation in DNA methylation profiles between human populations living in contrasted environements.
