Research Statement

During my PhD I was focused on studying the epigenetic and transcriptional regulatory circuitries that modulate hematopoietic cell differentiation pathways with particular attention to the key role of miR-223.

During my post doc I was focused on studying the molecular players and their roles in the regulation of the three-dimensional structure and spatial organization of chromatin via long-range interactions by using cutting edge technology of genome editing and chromatin conformation captures (4C-Hi-C).

As Staff Scientist at the Translational Immunology Section I am developing cutting edge immune monitoring assays essential to determine the immune responses in patients receiving immune therapies. Moreover, I am studying the cellular and molecular target of JAK inhibitors with focus on the epigenetic modifications induced by this class of drugs on immune cells.
