This story involved many hands over many years led by @BertCorrea3 and Saadlee Shehreen, PhD. Novel mechanisms of diversity generation in Acinetobacter baumannii resistance islands driven by Tn7-like elements academic.oup.com/nar/article/do…

Phenotypic heterogeneity is generated by passive mechanisms like noise in gene expression, right? Not always! Check out an ACTIVE mechanism for generating diversity in a clonal bacterial population: biorxiv.org/cgi/content/sh…

Our new paper out in PLOS Genetics today! Beautiful work by graduate student @ManuelaAlv95 in another fruitful and enjoyable collaboration with CavaLab! Want to know what peptidoglycan carboxypeptidases do? We lift the veil a little further. journals.plos.org/plosgenetics/a…

The Cava lab is hiring!! Two new positions are available in our interdisciplinary group located in the north of Sweden MIMS - Molecular Infection Medicine Sweden @UmeaUniversity If you are passionate about science then it is time to apply! Looking forward to your application! 🙂

Doerr lab star undergrad Ziyu Xue (Ziyu Xue on the right, future graduate student Cornell Microbiology) won the Robert Parker award for best Honors thesis for her work with Cornell Microbiology graduate student Nadia Nikulin (left) Congrats!

What an honor for Cassidy Prince and Cornell Microbiology to host Dr. Nancy Craig for our distinguished Portraits of a Microbiologist series. Thanks for returning to Wing Hall for such a moving and inspiring visit!

Huge Congratulations to Dr. Megan Renée Keller Megan Renee Keller for successfully and epically defending her PhD today! #proudPI Cornell BBS PhD Program

I asked AI to draw an image of the bacterial OM. This is what it came up with. My lab better pivot to the new hot field of outer pemmoccan homeostasis! And how is that one otter equally distributed among daughter cells? Lots of cool open questions!

Excited to kick off a bacterial genetics workshop at RIBB Kathmandu! We will be cloning some clinical NDM enzymes. ⁦Prajwal Rajbhandari🇳🇵⁩ ⁦Monima Karmacharya⁩ ⁦Gaurav Adhikari (he/him)⁩ ⁦Utsav Dahal⁩ @ankitsh03786959 ⁦Arjun Karki⁩

Announcing the 2025 Bacterial and Archaeal Cell Biology and Development Gordon Research Conferences. We have amazing speakers and discussion leaders confirmed and look forward to (again) having our minds blown by all the remarkable science. Applications will start being accepted in the fall.

And that concludes our workshop in Nepal! Successfully cloned NDM carbapenemases? Check! Isolated bacteria that can eat styrofoam and motor oil from Bagmati River AND fluoresce under UV? Check! Prajwal Rajbhandari🇳🇵 Monima Karmacharya Gaurav Adhikari (he/him) Utsav Dahal Ankit Shah

We demonstrated a lowcost device that can detect deadly bacteria in drinking water. It shows, once again, that worldclass research can flourish in Nepal, despite limited resources. Here is news release by Optica highlighting the important result. optica.org/about/newsroom…

Our new paper out in PLOS Pathogens today: dx.plos.org/10.1371/journa… We find that resistance/tolerance to antimicrobial peptides is slightly more complex and dynamic than your "average" antibiotic resistance. Nice work by Andrew Murtha et al.!

What a phenomenal seminar today at Microbiology & Immun by Hatzios Lab — a tour de force of using chemical proteomics to discover new mechanisms of redox signaling in gut infection!🤩🤩🤩

Latest preprint from our lab led by grad student Cassidy Prince and her undergrad mentee Bella Lin. She examines conservation and features of the programmed ribosomal frameshift in prfB. Presented by Cassidy at #GRC stress! biorxiv.org/content/10.110…

Congratulations to Dr. Manuela Alvarado Obando for an amazing PhD defense seminar! Felicidades, and on to more greatness! Cornell Microbiology @ManuelaAlv95 dx.plos.org/10.1371/journa… If you are looking for an exceptional postdoc (and are in the greater NYC area), reach out to her!
