I am super excited that our paper on inter-laboratory comparability of non-targeted LC–MS/MS analysis of dissolved organic matter was just published in ES&T. pubs.acs.org/doi/10.1021/...

Preprint from our lab and @func-metabo-lab.bsky.social: In synthetic nasal communities a single Corynebacterium propinquum strain can exclude Staphylococcus aureus through nutrient competition. www.biorxiv.org/content/10.6...

Community composition and strain identity drive metabolic competition and Staphylococcus aureus colonization resistance in Synthetic Nasal Communities

The human nasal microbiome is a low-diversity ecosystem whose assembly principles and mechanisms of colonization resistance remain poorly understood. In particular, Staphylococcus aureus colonization ...

New paper from our team: Led by @nike-wagner.bsky.social, we just published our findings on how the metabolite class of pteridines binds to the previously cryptic CutA protein. We used our native metabolomics approach to identify pteridines as ligands of CutA. www.pnas.org/doi/10.1073/...

We are super excited that our new paper on microfluidic-based LC-MS/MS fractionation in combination with bioluminescence bioreporters readouts, for compound-resolved bioactivity metabolomics, was just published: pubs.acs.org/doi/10.1021/...

New paper from the group. Together with Chambers Hughes, Giovanni Vitale and our amazing collaborators, we developed a multiplexed chemical metabolomics workflow to assign functional groups in non-targeted LC-MS/MS data: www.nature.com/articles/s41... Behind the paper story: go.nature.com/45ljV4d

Enhancing tandem mass spectrometry-based metabolite annotation with online chemical labeling - Nature Communications

To improve annotation in non-targeted metabolomics studies, authors develop a Multiplexed Chemical Metabolomics (MCheM) platform, combining post-column derivatization with integrated data processing. ...

We are super excited to start a new project with support from the Simons Foundation. We will leverage our metabolomics tools and SynCom models to study how microbes shape the production, transformation, and fate of marine DOM. Thanks so much @simonsfoundation.org‬ for making this possible!

Congratulations to our six new 2025 Simons Early Career Investigators in Aquatic Microbial Ecology and Evolution! See full list: www.simonsfoundation.org/2025/07/01/a... #science @systemsecology.bsky.social @daniel-petras.bsky.social @kendraturkkubo.bsky.social

We are pretty stoked that our paper on chemical shifts in kelp forests in the Gulf of Maine made it onto the front cover of ‪@science.org Big congratulations to Shane Farrell and everybody involved! ✌️✌️✌️

Science Magazine@science.org · last yr.

Kelp forests on the coast of Maine are in decline owing to rapid ocean warming and are being replaced by turf algae, which alter the ecosystem’s chemistry, hindering the recovery of kelp forests. Learn more in this week's issue of Science: scim.ag/4dwzl8j

Exciting invited talk by Daniel Petras @daniel-petras.bsky.social Functional #Metabolomics Approaches for Understanding Microbial Community Dynamics at the Molecular Level. #ICTC13 @func-metabo-lab.bsky.social

Another success story of native MS. Pteridines, found also in #cyanobacteria, bind to cutA, possibly bridging copper homeostasis and cellular redox regulation. doi.org/10.1101/2025... More about functional metabolomics at #ICTC13 from @daniel-petras.bsky.social (Invited speaker).

New reprint from the team: Lead by @nike-wagner.bsky.social, we used our native metabolomics setup to shed new light onto the function of the CutA protein. www.biorxiv.org/content/10.1...

Good news: We will have another summer school on non-targeted metabolomics this year! Organized by Martin Hansen and Scott Jarmusch, this year's summer school will be hosted at DTU in Copenhagen from August 18-22, inc. a summer camp style accommodation option at DTU. Sign up: tinyurl.com/NTMS2025

New preprint from our collaboration with @aliciaperezlorente.bsky.social from Diego Romero's group, who spend some time with us at @cmfi.bsky.social. It's great to see all the puzzle pieces coming together, providing a detailed snapshot of the molecular interplay between Bacillus and and Botrytis.

Alicia Pérez Lorente@aliciaperezlorente.bsky.social · last yr.

Excited to share our latest preprint! A fascinating story of chemical dialogue and microbial warfare: the Bacillus extracellular matrix acts as a key driver in the antagonistic interaction with Botrytis, while the fungus mounts a multi-layered defense. 🔗 www.biorxiv.org/content/10.1...

We are very proud that after a long repair/upgrade and moves across continents, our most critical piece of equipment is fully functional again. 💪💪💪 Big thanks to Jorge and Karo for fixing it and for generating the tutorial. ❤️ www.youtube.com/watch?v=Bf43...
