Gearing up for my first visit to @asm.org conference since 2011 in New Orleans, when it was called the General Meeting! I’m participating in a panel called: “Poster to Paper — Ask the Experts” on Sunday, June 7 from 11:15am–12:00pm ET. Hope to see you there or at your poster/session(s)!!! 🫡 #asm2026

From zoo wildlife to museum collections, the Smithsonian Institution reveals how microbes shape life across ecosystems. Don’t miss this first-of-its-kind session at #ASMicrobe 2026: eppro01.ativ.me/web/planner.... The event is also open to the public! Register here: myasm.asm.org/eweb/Dynamic...

Finally out! Biofilm ecology cannot forget their spatial structure 🦠🌏 Here we look at cm-scale diversity across controlled and uncontrolled conditions and quantify the effect of different sampling methods on the understanding of biofilm ecology doi.org/10.1093/isme... @eawag.bsky.social

🎊 New Preprint from phagefoundry.org ! Super excited to share our latest work on generating systematic phage-MDR P. aeruginosa interaction dataset & use of ML to predict phage susceptibility & phage cocktails from target genome sequences alone, w validations www.biorxiv.org/cgi/content/...

Hey all! Happy to finally join everyone here on Bluesky, and also to share the culmination of my longest-running postdoc project, now on bioRxiv: “Apparent generalism in Pseudomonas aeruginosa is underpinned by convergent cryptic specialization.” www.biorxiv.org/content/10.6...

Congrats to @cmuscience.bsky.social QBB grad June Qu on her pre-print for BTEXgenie, a tool that IDs BTEX (benzene, toluene, ethylbenzene, xylene) degradation genes in (meta)genomes. Tutorial: github.com/armbrusterla... Part of a new project in my lab inspired by Pittsburgh's brownfields. :)

My lab went outside! Check out this article (and video!) about a new project in my lab @cmuscience.bsky.social www.cmu.edu/mcs/news-eve...

👏👏👏

Congratulations, @animrprfct.bsky.social! Best of luck and looking forward to watching you present in the finals for 3MT! @cmuscience.bsky.social

How does treatment induced antibiotic resistance happen in real-world infections? We analysed 25k Pseudomonas isolates from 180 patients in a clinical trial to find out! TLDR: The ecological and evolutionary paths are surprisingly diverse & complex even in patients receiving identical treatment…

Congrats to Erin and Betsy for passing their qualifying exams last week!!!! Officially 3 PhD candidates in the lab @cmuscience.bsky.social now! 😎

Summer REU in biofilms! Pls share. www.binghamton.edu/centers/biof...

Congrats to Sean, Will, and co-authors! Shoutout to @cmuscience.bsky.social Quantitative Biology & Bioinformatics (QBB) MS student Isabelle D'Amico from my lab for her creative work on this cool collaboration!

Our last two guest lectures in Ecology @cmuscience.bsky.social were part of our theme thinking of infection as an ecologist (human = environment). First, Dr. Yasmin Hilliam (Bomberger Lab at Dartmouth) discussed how respiratory viral infection changes nutrients in airways, impacting microbiomes.

Our latest guest lecture in CMU Ecology class was Dr. Gus Ramirez (CalState LA @zombiephylotype.bsky.social) discussing research cruises, ocean biogeochemistry, & microbe-octopi interactions at sea mounts. Stunning & mind boggling to hear how you sample this stuff that is 1000s of meters underwater.

Today’s guest speaker in Ecology @cmuscience.bsky.social was perfect for Halloween: Arkadiy Garber @ironark.bsky.social from the McCutcheon Lab at ASU, discussing bacterial endosymbionts that support the junk food diets of sap-feeding insects! 😈

Microbiologist Paula Welander studies fossils, but not dinosaur bones or ammonite imprints. Instead, she looks for microscopic clues left behind by microbes that lived millions of years ago.

My department at UTK is hiring! 🧪🧫 We are hiring two Assistant Professors, one in Microbial Drivers of Chronic Disease and one in Quantitative Microbe-Plant-Environment Interactions! Come join our growing department of microbiologists. Knoxville is a great place to live!

We had our first guest lecturer in my Ecology class @cmuscience.bsky.social today! Dr. Delaney Miller from the Handelsman lab at Wisconsin Institute for Discovery (@widofficial.bsky.social) & HHMI gave an absolutely beautiful talk on how microbes in the rhizosphere impact plant development.
