Bioinformatics Genomics


Multicellular organisms establish and maintain different transcriptional states in disparate cell types through complex and specific regulation of gene expression. This regulation is mediated by the cooperative binding of transcription factors (TFs) to regulatory elements through the recognition of specific DNA sequence motifs. Additionally, the physical access of transcription factors to DNA can be modulated by epigenetic regulation, such as DNA methylation, nucleosome positioning and histone modifications. Failure to maintain this tight regulation of gene expression results in developmental defects and various diseases including cancer.

During this internship that could be extended into a PhD project, you will integrate genomic data (e.g. TF binding by ChIP-seq, gene expression by RNA-seq, chromatin accessibility by ATAC-seq, DNA methylation by WGBS) and sequence data (e.g. TF motifs) to study the sensitivity of transcription factors to DNA methylation. You will also develop deep learning approaches to better predict transcription factor binding sites in the context of DNA methylation.

You will work in an international environment at the IGBMC, a leading European institute. We are a team of computational and experimental biologists and you will benefit from our expertise in genomic data analysis (Anaïs Bardet) and modeling (Nacho Molina) for the success of the project.
