Identifying how chemicals shape microbial diversity through high-throughput ecological screens at University of Sheffield on FindAPhD.com PhD Project - Identifying how chemicals shape microbial diversity through high-throughput ecological screens at University of Sheffield, listed on FindAPhD.com

Do you have an interest in quantitative microbiology and interdisciplinary research? I'm recruiting a UK PhD student to develop high-throughput ecological screens to help us understand how chemical inputs impact microbial ecosystems: www.findaphd.com/phds/project...

Do you think transporters in E. coli contribute to metabolite release? No? Explore the effect of 66 different transporter knockout mutations on the exometabolome dynamics of ~300 metabolites yourself: keio.unil.ch

New preprint from our lab www.biorxiv.org/content/10.1...! Andrea Dos Santos and Clément Vulin combine experiments and models showing how adding glucose can strengthen negative interactions between microbial species. This can be used in tandem with antibiotic treatment to inhibit pathogens!

I'm delighted to announce that the Interdisciplinary Challenges (IntCha) meeting is returning in April 2026! Abstract submission is now open.
We encourage young scientists working at the interface between biology and physics to join us at the IESC in Corsica. Website here: intcha26.sciencesconf.org

Microbes release lower-value metabolites at higher rates Microbes release a wide range of metabolites into their environment, yet the reasons for this release and the factors that influence release rates are not well understood. Here, using a combination of...

Excited to share the first results from my postdoc at @dmf-unil.bsky.social with @saramitri.bsky.social

Three postdoctoral positions open (almost equally longitudinally spaced: one at @yale.edu with @martinadalbello.bsky.social , one at ELSI Tokyo with Shawn McGlynn, one with myself at ICTP in Trieste) to work collaboratively on www.dalbellolab.com/hfsp-project funded by @hfspo.bsky.social

Beautiful new review paper in preprint bridging microbial ecology and classic ecology led by Maggie Vogel, @olimeacock.bsky.social and @annasophieweiss.bsky.social, also by @juliensluneau.bsky.social and @lambdapp.bsky.social from our lab (not me :)) ecoevorxiv.org/repository/v...

For details and more interesting results on time to extinction, and it's coefficient of variation, check out the paper!

Motivated by some very kind reviewers, we also found that when populations are surviving in a metastable state before going extinct, their dynamics can be described effectively by a much simpler OU process, which promises easier ecological inference!

We see that deterministic control parameter for survival also plays a role in stochastic version. True to the spirit of statistical physics, probability to survive for different carrying capacities collapse onto a single surface controlled by rescaled initial abundance and distance to criticality!

Check out our recent paper just out in Physical Review E!
journals.aps.org/pre/abstract...
with Alice Doimo, @giorgionicoletti.bsky.social, Davide Bernardi
We look into stochasticity arising from finite carrying capacity in classical metapopulation models to understand survival statistics.

Our framework explaining why ecological interactions change between contexts is out in Ecology Letters!
A lovely collaboration with @saramitri.bsky.social which provides experimentally-testable links between the physiology and ecology of microbes.

Landscape and Environmental Heterogeneity Support Coexistence in Competitive Metacommunities, out in PNAS - we show that habitat heterogeneity is essential for species coexistence in models of dispersing metacommunities, fostering the emergence of ecological niches
