FGSEA is an R package that implements a novel algorithm for fast gene set enrichment analysis, based on Multilevel Monte Carlo Approach. The fast algorithm allows to achieve qualitatively higher precision in calculating GSEA P-values and allows more accurate pathway prioritization. Links: R package, source code, manuscript.


Phantasus is a web tool designed for visual and interactive gene expression analysis. In particular, it was designed to allow going from a typical dataset to differential expression and downstream analysis in an easy and streamlined manner. For that aim, Phantasus integrates an intuitive heatmap interface with gene expression analysis tools from Bioconductor. Links:, R package, source code, manuscript.


GAM and its upgrade GATOM are methods for integrated network analysis of transcriptional and steady-state metabolomic data focused on identification of the most changing metabolic subnetworks between two conditions of interest. Links: Shiny GATOM, source code, manuscript.
