The availability of high-throughput genomics data and the rapid development of synthetic biology techniques are changing the way we generate and test hypotheses on cellular functions and disease. Our research work focuses on developing algorithms to harness these technologies and answer fundamental biological and clinical questions.

Synthetic genomics

Computer Aided Engineering (CAE) methods

Recent advances in DNA synthesis technologies opened the path to engineer biological systems, from genes to pathways to entire eukaryotic genomes. We have been at the forefront in developing Computer Aided Design (CAD) software for synthetic genome engineering, such as BioPartsBuilder [Bioinformatics, 2016] and BioStudio [Science, 2017], which we used to build the first eukaryotic organism designed on a computer, the synthetic yeast (Sc2.0).

Our ultimate goal is to build biological systems at the same pace we have been designing electronic circuits for the past 30 years. Ironically, while there are groundbreaking advances in DNA synthesis and high-throughput screening platforms, current algorithms are not keeping up with the increasing design complexity of new synthetic systems. The lack of robust models to associate genotype to phenotype and a shortage of optimisation methods to sample the combinatorial genomic space represent the bottle-neck to automatic design of new biological systems. We are addressing these problems by designing phenotype prediction algorithms based on deep learning and combinatorial evolutionary optimisation methods to optimise biological systems recoding and assembly.

Working together with biologists, we aim at establishing a design-build-test framework for the rapid synthesis of any biological system.

Minimal genomes

Understanding the rules of life requires the identification of the building blocks supporting cellular life. At the genomic level, we are interested at the minimal set of genes required for cellular growth. As part of Sc2.0, we combined synthetic genomics and deep sequencing analysis to identify minimal genome patterns associated with wild-type fitness in yeast [Genome Research, 2016].

We are now interested in scaling up synthetic genomics and sequencing analysis techniques to study minimal genomes of mammalian systems to understand the fundamental rules of cell growth and differentiation.

Cancer biology

Genetics and genomics

Large scale cancer sequencing projects allowed us to explore the landscape of inherited and somatic mutations associated with cancer. To do that, we are taking a hierarchical approach putting these mutation into meaningful biological contexts, starting from genes up to pathways.

Using statistical learning, we characterised inherited pathways associated with increased cancer risks [Nature Rev Cancer, 2016] and inherited gene mutations associated with differential survival [Clinical Cancer Research, 2016]. We are now developing methods to analyse Genome Wide Association Studies (GWAS) at the gene and pathway level, and developing sequencing pipelines to identify rare mutations associated with relapse in multiple myeloma patients.

Pathway discovery

Most cellular functions are accomplished by complex interactions among proteins, it is necessary to evaluate cancer mutations in the broader context of the human interactome. We are developing data-fusion and network clustering algorithms that take advantage of big biological datasets to generate testable hypotheses of disease susceptibility, progression and outcome.

We have shown that statistical enrichment methods are powerful tools to identify key networks in cancer. We are now developing methods to identify statistically significant clusters of genes/proteins that associate with a phenotype using multiple layers of information (i.e. RNA-seq, Mass-spectrometry). We are studying angiogenesis and hypoxia as a response to different treatments.
