First week of sampling stingless bees in the Kinabalu National Park, Borneo. Together with collaborators from Universiti Malaysia Sabah, we collected bees from wild colonies as part of the GLOBEE project where we investigate the evolution of host-specificity in microbiome–host associations.

📢📢DEADLINE APPROACHING Abstract submission deadline for Cichlid Science 2026 closes this Sunday, May 31st. Don't miss the opportunity to submit yours! Early bird registration also closes on Sunday.

Happy to see this research published! It was a pleasure to contribute to this work led by Antoine Fages, Walter Salzburger and Patrick Tschopp 🎉

Evolution runs through the gut: Researchers show, using highly diverse cichlids, how diet shapes the composition of intestinal tissue. @tschopplab.bsky.social @snsf.ch

David Marques was an amazing speciation genomics researcher, a passionate birder, and a wonderful friend, husband, and father. May he rest in peace. www.nature.com/articles/s41...

New preprint from our lab! www.biorxiv.org/content/10.1... @aiswarya.bsky.social tested the role of priority effects in shaping the honeybee gut microbiota using an elegant combinatorial experimental design. A thread🧵....

🐝🦠 New paper: rdcu.be/eOf7A Phages may drive microbial diversity, yet we often don’t even know how phages & bacteria correlate in nature. Our new study tackles this in the honeybee gut, thanks to the great work of PhD student @malickndiaye.bsky.social at @dmf-unil.bsky.social @fbm-unil.bsky.social

Even the cichlid fish eggs of Lake Tanganyika are highly diverse! Picture by Grégoire Vernaz and Anja Haefeli www.horizons-mag.ch/2025/09/04/f...

1st of May five years ago, I started my PhD at the Salzburger lab in Basel, and yesterday I started my postdoc at the Engel lab in Lausanne! I’m grateful for these past five years and looking forward to this new opportunity!

🚨Our new paper, which was part of my doctoral research at the @unibas.ch, uses shotgun metagenomics to identify the diet of Lake Tanganyikan cichlid #fish, revealing an even greater diversity of food sources within their adaptive radiation! onlinelibrary.wiley.com/doi/full/10....

Last Friday, I defended my PhD work of the last 4 years and officially became a Doctor in Biology!! 🇨🇭🧬🐠🍤🍾 @unibas.ch

This is a video that I made about a year ago, as an alternative presentation on the EMPSEB28 conference. Have a look if you want to know more about my PhD study and what we did during our fieldwork at Lake Tanganyika: youtu.be/-4qbvGpVlv8?...
