Research Interests

One of the biggest challenges in biology is to understand how apparently identical cells respond differently to the same stimulus. We use state of the art genomic technologies to study the regulatory mechanism leading to the appearance of divergent gene expression programs in clonal populations of cells.

To reach that aim, our group combines experimental and computational work to develop novel genome-wide techniques to study eukaryotic transcription. We are specially interested in the case of drug-tolerant cancer persister cells that, although genetically sensitive to a drug, do not respond to it. To deliver an integrated view of the mechanisms driving their appearance, as well as to refine our knowledge of the basic process of gene expression, we study both budding yeast and human cell lines at three levels of the gene expression process: epigenetic status, transcript isoform usage and post-transcriptional mRNA regulation.
