Microbiomes
We investigate how microbial communities vary among animals and environments, and how they contribute to host biology, ecology and evolution.

How we work
We collect animals and environmental samples, run controlled experiments and analyse genomes, metagenomes and other molecular data together.

Research themes
Our projects examine microbiomes, their relationships with animal genomes and the spatial organisation of microbial communities at the smallest scales.
We investigate how microbial communities vary among animals and environments, and how they contribute to host biology, ecology and evolution.

We combine host genomic and microbiome data to understand how animals and their associated microorganisms interact and respond to ecological and evolutionary pressures.

We use spatially resolved molecular approaches to explore how microorganisms are organised and interact within the microscopic landscapes of their hosts.

Neotropical vertebrates
Exploring how gut microbiota may facilitate adaptive responses to different degrees of human disturbance in cloud-forest habitats.
How we do the work
We run animal experiments, process large sample collections with automated laboratory workflows and analyse the results on dedicated computing systems.

Captivity experiments reveal interactions between animals and their gut microorganisms under controlled conditions.

Automated tools enable consistent processing of hundreds or thousands of samples per project.

Dedicated life-science computing systems support our most demanding bioinformatic procedures.
