Leonor García-Bayona

I have a fabulous undergrad who has a lot of experience with QIIME2 & using R to analyze microbiome data. She is looking for a job starting in January. Would love to learn more bench and field skills (will be getting some in her last 2 months). Open to academic, industry, government jobs in the US.

Thanks for the kind words!

First publication from our lab!

Me cuentas cualquier dato útil que te pueda pasar para montar el lab :)

EXCELENTE!!! Felicitaciones!

Photo of Jaye Gardiner, a Black woman with long curly black hair, wearing dark green glasses and a coral colored sleeveless top, holding an iPad with the words “Jaye’s 1st day” written largely. Underneath it’s written “as an assistant professor 9/2/2025” although that doesn’t come out as clear in the photo.

Hello world! Today’s officially the first day of the lab! It’s an empty space currently only filled with ideas (that I don’t have card access to yet 😂) but I’m excited for the science that will happen here! -JCG

Prehistoric Global Migration of Vanishing Gut Microbes With Humans The gut microbiome is crucial for health and greatly affected by lifestyle. Many microbes common in non-industrialized populations are disappearing or extinct in industrialized populations. Understand...

Excited to share a new preprint w/ the Sonnenberg lab, led by Matt Carter, @zzzhiru.bsky.social & @mattolm.bsky.social. We analyzed the microbiomes of two non-industrialized populations from opposite sides of the globe to try to reconstruct the recent evolutionary history of our gut microbiota.

Snails with human-like eyes?!

Published in @natcomms.nature.com, the @planaria1.bsky.social & @accorsi-alice.bsky.social Labs have established apple snails as a novel model for studying vision restoration. They have complex camera-type eyes & the ability to regrow them in 28 days: bit.ly/4mvaxkq

"feels like" is correct because it gives the IMPRESSION of expertise. Just asked GPT5-Thinking a few questions I had asked my PhD students this week... let me tell you, our jobs are safe in this regard LOL
If you believe what it says, it's on you.

Keep in mind that this one only takes their super expensive proprietary tips. Or if people have found a way around it please let me know!

Congrats to postdoc Zhe Zhou on her paper out today in @cp-cellhostmicrobe.bsky.social showing that gut bacteria cross-feed a common dietary antioxidant to produce energy under anaerobic conditions. Thanks to collaborators Angela Jiang and Xiaofang Jiang at NIH.

Microbiology professor, want to join a slack for microbiology professors, any career stage, diverse career types (pure teaching, med school, R1, community college, pure research fed PIs, ...)

Message me for an invite link if you are interested.

No imposter syndrome, if you are 1% micro, join!

Junior, Assistant, or Associate Specialist – Xue Lab University of California, Irvine is hiring. Apply now!

The Xue lab at UC Irvine is looking for a staff scientist to support our work investigating how microbes interact and evolve in the gut microbiome! Open to a wide range of previous experience levels, see ad for more.

Ahhh, fair 🤣

ohh so what you're saying is I should find myself a long conference so that I can finally get my grant writing done... 👀🧠

Thrilled to share the first preprint from my group! Prevotella are predominant but understudied members of the respiratory microbiome. They have a reputation for being hard to work with, but understanding them is likely important for understanding how they contribute to respiratory health. 🧫🔬

Yet again burned by the "this Friday" vs "next Friday" ambiguity. whyyyyy English language, whyyyy

Huge congrats!!!

Any friends going to ASM Microbe? Let me know so we can catch up!!

Fluorescent microscopy image of donor cells (shown in green) and recipient cells (shown in dark blue). Light blue cells are transconjugants. Transconjugants are only next to donor cells.

Cool paper showing 🦠 recipient response to #plasmid conjugation

Capsule blocks conjugation, preventing MPF between donor:recipient. However, conjugation exploits recipient strain heterogeneity of capsule thickness, conjugating to cells with less capsule

The Koonin Law of Computatoinal Biology:

Whenever you think you have a great idea in computational or evolutionary biology, it will already have been published by Eugene Koonin in the mid 90ies.

We have two new positions, a PhD and a Post doc at #InstituteofBiologyLeiden within our @microclockerc.bsky.social #ERCSyG project to discover interaction of #circadianclocks between Bacillus subtilis and Arabidopsis

please share these with your network! 🙏

Thanks for your wonderful visit and telling us about you cool reserach! LOL and for featuring my lab hammock 🤣

Tweeps, please spread the word. We're still looking at recruiting a structural biologist (any level) to study plant-pathogen protein complexes especially in the context of coevolution. Direct inquiries welcome.

Please include a cover letter.

Biofilm architecture determines the dissemination of conjugative plasmids: We measured the spatiotemporal spread of plasmids in biofilms and found that plasmids only spread in some biofilm regions!
