Research

Diseases are caused by a complex interplay between different factors, such as genetics and the environment. A deeper understanding of the genetic risk factors of complex diseases can enable the development of more personalized treatments and prevention strategies.

Our research is focused on developing novel machine-learning methods to advance key computational aspects of precision medicine. We have a particular focus on the integration of genetic studies with relevant molecular patterns extracted from multi-omics data. For this, we aim to develop the next generation of methodologies that will consolidate large and heterogeneous sources of biomedical information to extract biological insight to ultimately improve human health.

Strongly committed to open source and open science, we use GitHub for the development of reproducible workflows and Manubot for the transparent authoring of modern and collaborative scholarly manuscripts.

Here we introduce the PhenoPLIER framework, an omnigenic approach that integrates genetic studies (GWAS/TWAS) with gene modules learned from expression data. PhenoPLIER provides 1) a regression framework that computes an association between gene modules and diseases, 2) a clustering approach that finds groups of diseases with shared transcriptomic properties, and 3) a gene module-based drug-repurposing method.

This article introduces the Clustermatch Correlation Coefficient (CCC), an efficient, easy-to-use and not-only-linear coefficient based on machine learning models. CCC can detect biologically meaningful linear and nonlinear patterns missed by standard, linear-only correlation coefficients.
