Sabbatical output #3. I have learnt a lot about metabolomics and its application in forensics. pubs.acs.org/doi/10.1021/...

Sabbatical output #2. I had the privilege to support colleagues from Ghana with their work on antibiotic resistance. www.frontiersin.org/journals/mic...

Sabbatical output #1. I had the opportunity to learn much about plan iron nutrition and could help to extend the concepts of siderophore-mediated interactions from microbes to plants. www.nature.com/articles/s41...

After long radio silence, I have decided to come back to bluesky and post about our work. 2025 was mainly shaped by my sabbatical and excursions into other research domains. In 2026, it’s time to move back to my core work on bacterial interactions. 👇 kuemmerli-lab.weebly.com

We are looking for a highly motivated postdoc to work on pathogen interactions. Please send in your application via jobs.uzh.ch/job-vacancie...

My sabbatical has started!

New preprint! How S. aureus copes with inhibitory compounds secreted by P. aeruginosa. By @schluk.bsky.social. Great collaboration with @fgcz-en.bsky.social www.biorxiv.org/content/10.1...

New paper out in ISME Journal. Social interactions between strains shape bacterial communities. However, their impact on community functioning is lower compared to basic strain identity features. @joskramer.bsky.social @alexfig.bsky.social @simonmarech.bsky.social academic.oup.com/ismej/advanc...

Strain identity effects contribute more to Pseudomonas community functioning than strain interactions #ISMEJournal by @joskramer.bsky.social et al from @rkmicrobes.bsky.social academic.oup.com/ismej/advanc...

We derive iron-siderophore interaction networks among Pseudomonas strains from sequencing data. One key insight: natural strains form dense networks, whereas pathogens are loners. With @frimanscience.bsky.social @zhiyuanli.bsky.social & Nanjing colleagues www.science.org/doi/10.1126/...

Are #pyoverdines effective antibacterials?🦠💊 Yes! We found strong competitive and antibacterial effects against #ESKAPE pathogens via iron depletion.

Wonderful pre-X-mas group activity in Arth-Goldau Wildlife Park.

Why we should have more lab cleaning days.

My group (secretly) nominated me for the UZH Montoring Award. I feel deeply honoured and flattered. It means a lot to me. Many thanks.

Proud to have been involved in this great project lead by @simonahuwiler.bsky.social and Subham Mridha on predatory bacteria and the resistance they trigger in their prey. www.biorxiv.org/content/10.1...

I have abstained from social media for quite some time. Now, I make a new effort - especially for the sake of my students and postdocs who accomplish outstanding things and keep the lab going.

Superb visit at #eawag yesterday discussing cool projects. Thanks Chujin Ruan, group of Dave Johnson for the invitation 🙏 Nice to also meet up with @rkmicrobes.bsky.social, Serina Robinson, and Eleonora Secchi!

New preprint from our lab. Bacterial social interactions are common. But to what extent do they contribute to community functioning compared to basic species identity effects? Check it out 👇 www.biorxiv.org/content/10.1...

I am recruiting a PhD student to work on microbial communities in Arctic ecosystems. This is a great opportunity for someone interested in combining field, lab, and computational approaches. If you are interested, message me for more information.

This paper was really fun to write! Unpicking the subtle differences between dependencies, facilitation and cooperation in microbial communities, and why it matters. With Elze Hesse (not here yet!)

Please share: The Stubbendieck Lab is hiring a postdoc to study microbial competition & secondary metabolism in human microbiomes. Experience in natural product chemistry or BGCs preferred. For more info and to apply: apply.interfolio.com/141377

PhD student opening! We are collaborating with the team of David Johnson @EawagResearch to understand E. faecalis polymicrobial community assembly, interactions, and consequences for AMR and infection. Details of the position and how to apply can be found here: tinyurl.com/ywa52a6a.

We work with zebrafish! Our first (method) paper on polymicrobial infections, real-time imaging and automated data analysis with this exciting model host. Now out on bioRxiv. Guided by @microbedesi.bsky.social www.biorxiv.org/content/10.1...

For many years, we have worked on cooperative aspects of siderophore sharing. Here, we show that siderophores from environmental pseudomonads can have strong competitive and antibacterial effects against pathogens through the induction of iron starvation. elifesciences.org/reviewed-pre...

End-of-year lab cleaning. Great group effort - everybody helped (except the PI who sat in this office and reviewed manuscripts and grant proposals 🫤)

Fantastic performance by Désirée Schmitz during her PhD defence. Congratulations and all the best for your future!

Together with @frimanscience.bsky.social and our Chinese colleagues, we have worked out how to predict (i) siderophore molecular structures www.biorxiv.org/content/10.1... and (ii) siderophore interaction networks in communities www.biorxiv.org/content/10.1... from sequence data!

Hello! I'm new on Bluesky. I will mainly post about microbe-related science (by others and us).
