Happy that our work on the evolution of Yellowstone cyanobacteria is now published in @elife.bsky.social: doi.org/10.7554/eLife.…! Did a lot of work in revision—many thanks to the anonymous reviewers for great suggestions! Also see the digest for summary: elifesciences.org/digests/90849/…

Very excited our recent work with Daniel Fisher and @BhayaDevaki on long-term coevolution of natural cyanobacteria is up on bioRxiv. Instead of diverging into specialist strains, we find different species slowly merge on timescales of 100k years. (1/n) doi.org/10.1101/2023.0…

New preprint to close out the year! Led by Alana Papula and together with Daniel Fisher, we used single-cell genomes to infer the evolution of Prochlorococcus—one of the most abundant and genetically diverse bacteria on Earth. Check it out here: doi.org/10.64898/2025.…

We have a funding for postdoctoral fellowship that needs to be filled ASAP. We are exploring new directions (1) at the interface of non-equilibrium computations and physical learning and (2) in building ecologically motivated AI models for microbiomes. Please spread the word!

‼️I'm looking for postdoc‼️Join effort using metagenomes to quantify microbial catabolic potential and carbon substrate availability at the ecosystem level. We seek to understand evolutionary forces shaping the C cycle. Part of ccomp-stc.org careers.peopleclick.com/careerscp/clie…

#SyntheticBiology postdoctoral position in our group @ufhorticulture in directed evolution of enzymes that underlie important crop traits ⬇️

Very excited to share final version of our paper! What forces shape evolution of cross-feeding among planktonic ocean microbes, and how does it in turn drive self-organization of biogeochemical cycles? These are the questions we explore here: science.org/doi/full/10.11…

📢📣Are you a young scientist excited by sustainability, algae, and bioenergetics? We have a new opening for a junior research associate position to join our team👇 Please RT🤗 jobs.carnegiescience.edu/jobs/junior-re…

please spread the word about this theoretical population biology workshop in chicago in june! should be really fun nitmb.org/modeling-and-t…

After a long and winding odyssey, excited to finally drop anchor in open-access waters. This preprint shows how neutral allele frequency time series can illuminate disease transmission rates between communities— key for epidemic fore- & backcasting. medrxiv.org/content/10.110… 🧵

Thrilled to share that I'm starting my own lab at UC Irvine in April 2025 and am recruiting at all levels - please spread the word! My lab will study how microbes interact and evolve in complex communities like the human gut microbiome. kxuelab.com 1/2

@clabreu Congrats Clare! Well deserved!

Please RT! Looking for bioinformatics technician to study how diversity of heterotrophic metabolisms shapes ocean C cycle. Part of ccomp-stc.org. Collaborative, open, team science. Opportunity to gain research experience before graduate school. careers.peopleclick.com/careerscp/clie…

@PetrovADmitri Thanks, Dmitri!

Congratulations! And for all people looking for an incredible lab to join, run TO this opportunity!

Very grateful to my mentors & collaborators—Kirill Korolev, @ohallats, Daniel Fisher, @BhayaDevaki—and the many friends who have helped along the way. Hope to see you all in Florida!

Very happy to announce I’ll be joining the physics dept @UF in the Fall as an assistant professor! Our group will study eco-evo dynamics of marine microbial communities, using theory & data analysis. Will be looking for students & postdocs so definitely reach out if interested.

Excited to share a preprint describing the relationships of B cells resident in a range of human immune organs, with lessons about the pace of immune memory formation! Massive, really fun effort with @mswift_science and @StephenQuake biorxiv.org/content/10.110…

relative to selection with standard population genetics theory is not clear. Presumably spatial structure within the population plays an important role in determining the effective selection and recombination rates, but precisely how this happens is still a mystery. (n/n)

Selective sweeps with high rates of recombination could explain how long segments that are transferred initially could be broken up into the blocks we observe fast enough so that mutations could not have accumulated. But how to reconcile the high recombination rates (17/n)
