Quote Mathilde Poyet: My research focuses on developing advanced methodologies to deeply investigate undercharacterized human-associated bacterial species and expanding our understanding of the human gut microbiome’s diversity, evolution, and impact on health across globally diverse populations.

Quote Mathilde Poyet: I enjoy working in science because it combines curiosity, teamwork, and openness, and gives me the opportunity to build inclusive collaborations across cultures and disciplines, while discovering something new every day.

To mark the International Day of Women and Girls in Science #11February, we'll be introducing several female scientists from Kiel University over the next few days.

How does industrialization and lifestyle impact our interactions with gut microbiomes? And what is the consequence of these perturbations on our physiology?
Discover findings from our new study addressing these questions:

Convergent genomic responses of human gut bacteria to variations in industrialization To what extent gut bacteria respond to the distinct ecological pressures imposed by human lifestyle remains unclear. Here, we investigate how genomic adaptation in gut bacteria differ between industri...

Do gut bacteria evolve differently in industrialized vs. non-industrialized humans?
Our new study reveals that industrialization drives parallel genomic adaptations across gut bacterial species worldwide:

Gut microbiota profiles of peninsular Malaysian populations are associated with urbanization and lifestyle - Scientific Reports Scientific Reports - Gut microbiota profiles of peninsular Malaysian populations are associated with urbanization and lifestyle

New publication from the Global Microbiome Conservancy @mmmicrobiomelab.bsky.social!
Leveraging our dataset from Peninsular Malaysia, we report a clear stratification of microbial community structure, diversity and composition, along the rural–urban gradient.

This paper has been a long time coming: We looked at the genomes of historical bacterial samples over a century to look for trends of antibiotic resistance genes, finding multiple instances of them in infections before the age of antibiotics, but an increase in both frequency and mobility after

Check out this amazing preprint from my @isbscience.org colleague @annabiosys.bsky.social's lab!

Gupta et al. captured the entire infection cycle of an uncharacterized phage through single-cell RNA-seq of a B. fragilis population (capturing cells at different points in the infection cycle). 🤩
