I am Team Leader at the Center for Genomic Science, an outstation of the Istituto Italiano di Tecnologia (IIT) located within the IFOM-IEO campus in Milan. My background is in biotechnology and bioinformatics (University of Milano-Bicocca, and University of Torino). I returned to Milan following a couple of Postdocs in the USA, at the Yale University (2007- 2009) and at the Salk Institute (2009-2011).
Since 2011 I am working here as an independent investigator, leading the “Epigenomics and Transcriptional Regulation” research group. The group is currently composed of 3 postdocs and 1 PhD student, and is highly interdisciplinar (half computational and half experimental).
We study the dynamics of transcriptional regulation, and their epitranscriptional and epigenetic determinants. We approach this field by employing cutting edge computational and experimental approaches, including RNA metabolic labeling, mathematical modeling, and high-throughput sequencing. Among various interests we aim at identifying factors bridging between chromatin and epitranscriptome, and how the epitranscriptome mediates aberrant transcriptional programs in liver cancer and in other disease models.

In this study, which was selected as cover for the October issue, we provided an unprecedented analysis of the RNA and RNAPII dynamics, which we used to dissect the (post- )transcriptional responses to acute MYC activation. This allowed us to shed light on the role of MYC as repressor, and to connect it with the dynamics of RNAPII recruitment.

In this study we provided the first software able to comprehensively quantify the RNA dynamics through the integrative analysis of total and nascent RNAs.

In this study we comprehensively characterized MYC-dependent transcriptional and epigenetic land- scapes, thus revising the recent concept of MYC as transcriptional amplifier.

In this study, which was recognized by ScienceWatch as the #4 hottest paper of 2011, we characterized the limits of epigenome reprogramming in the generation of iPSCs.
