Computational Multi-Omics

Research Interests

Our mission is to understand the (epi)genome biology and its impact on pathological conditions using computational multi-omics approaches. Such methods rely on the statistical analysis and integration of big data (high-throughput sequencing, microarrays, proteomics, high-throughput screening) and clinical/phenotypic data.


The regulation of (epi)genome and transcriptome networks is a crucial component of a healthy cell, but it is relatively unknown the molecular mechanisms underlying its misregulation in diseases: from cancer to age-related disorders. We have been deciphering pathological conditions through multiomics approaches, identifying molecular events to be further used as biomarkers and therapeutic targets.

Research Highlights
Unveiling the complexity of cell biology and underlying disregulation of diseases by deciphering multi-omics data

Through muti-omics profiling of a prospective cohort of 136 colorectal tumor biopsies we unveiled that mutational and chromosomal instability concertedly shape genetic and microenvironmental tumor heterogeneity (Sobral et al 2022, Communications Biology). Moreover, we demonstrated that tumor heterogeneity can be a prognostic marker of tumor relapse, where clonal diversity driven by large copy number alterations favors metastatic potential and multiple events of metastatic seeding. Overall, our findings unveiled that clonal diversity can influence microenvironment heterogeneity, differing across colorectal tumor subtypes and influencing tumor evolution and metastasis progression.
