Research Interests

Genomics of gene expression

One of the biggest challenges in biology is to understand how apparently identical cells respond differently to the same stimulus. We are especially interested in understanding how the intrinsic complexity of gene expression contributes to non-genetic cellular adaptation. To deliver an integrated view of the mechanisms driving the appearance of divergent cellular phenotypes, as well as to refine our knowledge of the basic process of gene expression, we study: the epigenetic status, transcript isoform usage and post-transcriptional mRNA regulation.

In addition to our interest in the fundamental dissection of gene expression, our lab actively develops novel sequencing technologies. We have developed a diversity of approaches to study gene expression, chromatin organization and to improve clinical analysis. We investigate the complexity of overlapping human transcript isoforms simultaneously sequencing both the 5’ and 3’ ends of each RNA molecule (TIF-Seq). Our lab has also shown how the existence of widespread co-translational mRNA degradation allows studying ribosome dynamics by sequencing mRNA degradation intermediates (5P-Seq). By combining experimental and computational biology, we aim to decrease the gap between research fields and contribute to a better mechanistically understanding of the gene expression process.
