- Senior Manager, Genomica
Il mio principale interesse di ricerca è lo sviluppo e l’applicazione di metodi basati sul sequenziamento del DNA e sulla microscopia a fluorescenza per studiare l’interazione tra struttura, funzione e fragilità del genoma in condizioni di salute e malattia, con particolare attenzione al cancro. In questo ambito, sono fortemente impegnato nello sviluppo di metodiche di facile impiego ed economicamente vantaggiose che possano essere tradotte in utili applicazioni cliniche.
Nel corso degli anni, ho sviluppato numerosi strumenti, tra cui il primo metodo per la mappatura a livello genomico delle rotture del doppio filamento di DNA (BLESS, Nat Meth 2013) e i suoi miglioramenti a valle (BLISS, Nat Commun 2017; sBLISS, Nat Prot 2020), nonché una serie di sequenziamenti (CUTseq, Nat Commun 2019; GPSeq, Nat Biotechnol 2020; COVseq, Nat Commun 20221) e metodi basati sulla microscopia (HD-FISH, Nat Meth 2013; FuseFISH, Cell Rep 2014; RollFISH, Comm Bio 2018; iFISH, Nat Commun 2019; FRET-FISH, Nat Commun 2022) per studiare vari aspetti della struttura e della fragilità del genoma.

COVseq is a cost-effective workflow for mass-scale SARS-CoV-2 genomic surveillance
While mass-scale vaccination campaigns are ongoing worldwide, genomic surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical to monitor the emergence and global spread of viral variants of concern (VOC). Here, we present a streamlined workflow-COVseq-which can be used to generate highly multiplexed sequencing libraries compatible with Illumina platforms from hundreds of SARS-CoV-2 […]

GPSeq reveals the radial organization of chromatin in the cell nucleus
With the exception of lamina-associated domains, the radial organization of chromatin in mammalian cells remains largely unexplored. Here we describe genomic loci positioning by sequencing (GPSeq), a genome-wide method for inferring distances to the nuclear lamina all along the nuclear radius. GPSeq relies on gradual restriction digestion of chromatin from the nuclear lamina toward the […]

CUTseq is a versatile method for preparing multiplexed DNA sequencing libraries from low-input samples
Current multiplexing strategies for massively parallel sequencing of genomic DNA mainly rely on library indexing in the final steps of library preparation. This procedure is costly and time-consuming, because a library must be generated separately for each sample. Furthermore, library preparation is challenging in the case of fixed samples, such as DNA extracted from formalin-fixed […]

iFISH is a publically available resource enabling versatile DNA FISH to study genome architecture
DNA fluorescence in situ hybridization (DNA FISH) is a powerful method to study chromosomal organization in single cells. At present, there is a lack of free resources of DNA FISH probes and probe design tools which can be readily applied. Here, we describe iFISH, an open-source repository currently comprising 380 DNA FISH probes targeting multiple […]

BLISS is a versatile and quantitative method for genome-wide profiling of DNA double-strand breaks
Precisely measuring the location and frequency of DNA double-strand breaks (DSBs) along the genome is instrumental to understanding genomic fragility, but current methods are limited in versatility, sensitivity or practicality. Here we present Breaks Labeling In Situ and Sequencing (BLISS), featuring the following: (1) direct labelling of DSBs in fixed cells or tissue sections on […]
