Welcome to the Comparative Genomics & Metagenomics Lab

We study microbial diversity, microbiome ecology, and evolution using comparative genomics, metagenomics, and phylogenomics. Our work spans the rare biosphere, plant microbiome, functional genomics, and the development of open bioinformatics tools.

Highlights

MBE

TreeProfiler: large-scale metadata profiling along gene and species trees.

Mol Biol Evol Feb. 2, 2026

TreeProfiler is a command-line tool that annotates any phylogenetic tree with metadata (ecology, taxonomy, phenotypes) and lets researchers visualise and query patterns across thousands of tips at once.

Research Lines

Rare biosphere

Studying low-abundance microbial taxa and their roles in ecosystem function and evolution.

Plant Microbiome

Investigating the microbiomes associated with plants and their interactions in the rhizosphere.

Microbial Biodiversity

Characterizing the full extent of microbial diversity across Earth's habitats and ecosystems.

Functional Genomics

Unraveling the functions of microbial genes and proteins across diverse genomic contexts.

Unveiling the hidden biodiversity of microbial chemoreceptor genes in the rare biosphere

bioRxiv June 24, 2025

A deep dive into environmental DNA databases reveals that chemoreceptor genes—bacterial sensors for chemical signals—are far more diverse and widespread in rare microbial communities than previously thought.
