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! 😈

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.

Headed home after a fabulous week in RI for the Microbial Adhesion & Signal Transduction GRC. We even had a critical mass of Parsek/Woz alums for a photo!

Congratulations to CMU Bio undergrad Olivia for getting into her top picks for dental school and to Jot (my lab’s first student 🥲) for successfully defending her honors thesis in the Quantitative Bio & Bioinformatics (QBB) Master’s program!!! Today is a good day.

The Armbruster Lab is officially open in the Department of Biological Sciences at Carnegie Mellon University in Pittsburgh! We're studying how bacteria in biofilms persist in the built environment & transition into the host to cause infections. Happy to be here! 🤓

Rite of passage for micro postdocs transitioning to faculty: replicate a Tn library! Grateful to be wrapping up at the same time as @fabricejpierre.bsky.social (also starting his lab in Jan) so we can compare notes & team up on pipetting. Thanks to Sophie and my labmates for helping, too!
