1/ Our new paper is out in PRX Life. Physicists' often treat microbiomes as disordered systems with coexistence in very high-dimensional niche spaces. We asked whether empirical data supports this picture, and found the data point somewhere else: journals.aps.org/prxlife/abst...
journals.aps.org
Low-Dimensional Coexistence in Complex Microbial Ecosystems
Analysis of nearly 200 human gut microbiome datasets shows that microbial coexistence is governed by a few effective ecological dimensions, rather than the high-dimensional niches assumed by prevailing theory.

Over the past year, I’ve been thinking a lot about functional redundancy. A concept that seems so intuitive it almost feels boring, until you really start thinking it through. So excited to see the results of this brain-twisting thought process now out 🥳 authors.elsevier.com/sd/article/S...

Very happy to share that the work I've been doing with @saramitri.bsky.social is now out on biorxiv! www.biorxiv.org/content/10.6... We broadly ask how are microbial interactions distributed, is there a common shape across datasets, what drives it, and why it matters. Summary thread below 🧵 1/17

Metabolic processes shape microbial interaction distributions
Microbial communities are largely driven by metabolic interactions, whereby species compete for shared resources and exchange byproducts. Such interactions are commonly classified by their sign alone....
