Excited to share that I've been awarded a 5-year NIH MIRA (R35) from the National Institute of General Medical Sciences! The lab is growing! We're recruiting postdocs and research techs interested in microbial ecology, quantitative microscopy, microfluidics, and molecular biology. Please share!

Excited to share our new paper! Emanuele and @benjaminraach.bsky.social combine experiments and modelling to show that phage-mediated lysis can increase the growth rate of surviving bacteria by releasing resources back into the environment. 👇 www.cell.com/iscience/ful...

Very excited to share our new preprint, led by Alyssa Henderson! We ask why auxotrophy is so widespread in bacteria, and find that phylogeny is the dominant predictor of autotrophy, as opposed to environmental context. Check it out! 👇

Amino acid auxotrophy is a feature of a distinct bacterial lifestyle across environments
Amino acid auxotrophy, the loss of biosynthetic potential for an amino acid, is a highly prevalent feature of microbial life, yet the evolutionary processes driving its distribution in nature remain u...

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. onlinelibrary.wiley.com/doi/10.1111/...

Environment‐Organism Feedbacks Drive Changes in Ecological Interactions
Ecological interactions are central to our understanding of the composition and function of communities, but attempts to use them as a theoretical foundation for experimental ecology have been confou....

Thrilled to announce that Matthias Hülsmann's new perspective is now out in @naturemicrobiol.bsky.social! This exciting work is shaping how our group thinks about collective microbiome metabolism. Check it out! www.nature.com/articles/s41...

A framework for understanding collective microbiome metabolism - Nature Microbiology
This Perspective explores why microbiome members perform partial metabolism of substrates and suggests that proteome efficiency is a driver of collective microbiome metabolism.

My friend & colleague @micsysecolab.bsky.social Matthias has written this extremely insightful and fascinating perspective on bacterial collective metabolism, out now in @naturemicrobiol.bsky.social. So happy to see this out & super excited for proteome allocation! www.nature.com/articles/s41...

For me an amazing aspect of this discovery was going back to the roots of microbiology: observing cells under the microscope. When T6SS killers were present along with prey on a carbon source that both types can metabolise- the killers wiped out prey cells
