🇲🇫 Postdoc with @saramitri & @simon_vanvliet 🇨🇭 | Microfluidics 🤩 | Interested in bacterial ecology, plant-pathogen-microbiota interactions & agriculture
Lausanne, Switzerland
Joined October 2017
Very happy to have contributed to this cool work spearheaded by @nieves_lpg @type3lab! Nice investigation of Pseudomonas syringae T3SS & Flagella expression dynamics during leaf infection, with spatial and temporal patterns emerging in the apoplast 🌱🦠🔬 https://t.co/Prb47xxi7g

Thrilled to finally share! The plant microbiota triggers dose-dependent immune responses that feed back to influence bacterial colonization. This affects non-pathogenic and pathogenic strains, impacting microbiota homeostasis. Out today in @NaturePlants:

Nature Plants - The plant general non-self response system is triggered by leaf microbiota members and, in turn, impacts their colonization.

#Xanthomonas pathogens are stuck in hydathodes for weeks(!) and cannot traverse to the xylem vasculature if they lack four specific cell wall degrading enzymes. Tremendous effort and beautiful “Xantho-blots” by @MishaPaauw @HAvandenBurgLab

To colonize plants, pathogenic bacteria modulate the biology of the host employing different bacterial secretion systems. For example, the type II secretion system (T2SS) releases toxins, proteases,...

Thank you @JohnInnesCentre @SusanSchlimpert for organizing this symposium! I had a really great time sharing my research, listening to amazing talks and discussing with the vibrant community here 🦠🌱 And thanks to @nobolly for the nice chat & showing me around @TheSainsburyLab
We’re excited to be kicking off our Early Career Microbiologists Symposium 2024 🌟 Following an introduction from Graham Moore, JIC Director, our morning session is chaired by @SusanSchlimpert and begins with a talk by Anna Brogan @harvardmed

We did some time-lapse imaging in vitro to visualize #PhenotypicHeterogeneity for flagella expression in single cells and quantify the growth cost associated (with the help of @simon_vanvliet 💪) More details on the regulation of this behavior in the paper if you're interested🤓

Very important and comprehensive review! It's really nice that you included both the plant's and the pathogen's perspective in the context of climate change👌 Congrats @CharlesRLev & co !! 👏

Super happy to share the 1st paper of my PhD. Out in @FEMSmicro, with the incredible @MicrobialMarie and more. Using SynCom inoculation on seeds, we characterized their transmission to seedlings. SynComs strongly outcompeted potting soil microbiota.🦠1/8 https://t.co/U8MKlz4Gcy

New pre-print! My first research project with @saramitri is now live. Interactions underpin our understanding of ecosystems, but can change in hard-to-explain ways. Here, we show that many of these variations can be predicted from underlying mechanisms:

Ecological interactions, the impact of one organism on the growth and death of another, underpin our understanding of the long-term composition and the functional properties of communities. Interac...
