Project description: DNA replication must adapt to changes in chromatin organization associated with cell differentiation and development, whose deregulation can challenge genome stability and leads to mutations, cancer and many other genetic diseases. Our team focuses on developing cutting-edge high-throughput genomic approaches and using genome-wide data analyses to study the spatio-temporal replication program of the human genome, and how its deregulation causes genome instability and leads to human diseases. Recently, we have published several pioneer papers showing how gene transcription shapes the replication landscape of human cells and how transcription-replication conflicts lead to genome instability, which is amongst the key factors playing an important role in cancer development.

We are looking for a motivated bioinformatics master student, who likes teamwork and interaction with both experimental and computational biologists. The candidate will develop the bioinformatic tools and perform the analysis on the high-throughput genome-wide data of the human replication, gene transcription and genome instability, and then compare with the mutational data (both point mutations and structure variations) obtained from cancer genomics projects, in order to gain better insight in understanding the replication stress associated mutational signatures in cancers. The student will be placed in an excellent multidisciplinary environment of the Institut Curie. He/she will work in close collaboration with the worldwide experimental and computational biology experts and tightly interact with the bioinformatics/sequencing platform of Institut Curie.
