Come join us in Breckenridge! 👇🏽

Yes! Looking forward to it.

Happy to announce that I have been promoted to Associate Professor with tenure at VUMC. What a wild and fun ride it has been… I couldn’t have achieved this without my amazing trainees’ dedication, my family’s patience and the support from colleagues and mentors. Let’s keep swimming. Cheers 🥂!

Friday we lost a brilliant mind, colleague, and friend to her battle with pancreatic cancer. Those who knew her will remember Helene Andrews-Polymenis for her warmth, generosity and leadership. She will be missed by many. RIP

Microbiota shape the colon epithelium controlling inter-crypt absorptive goblet cells via butyrate–GP R109A signalling The colonic epithelium is a key interface between the gut microbiota and the host. How microbiota-derived signals influence epithelial cell identity and function remains incompletely understood. He...

Huge thanks to @asm.org for this recognition. Congratulations to all 2026 ASM Awards winners! 🍾👏🏽🥂

Thanks, Matt!

Thank you so much, Michael!

Honored to have received the 2026 ASM Award for Early Career Basic Research. This award is also a recognition of my phenomenal trainees and their hard work. Thank you to the mentors that have supported my career and those who have nominated me for this award.

@kellydoran.bsky.social giving an amazing talk at the HMB Track Hub at #ASMicrobe!

Congratulations to all the new @bwfund.bsky.social investigators in the pathogenesis of infectious diseases. Especial shout-out to dear friend @joeyzacks.bsky.social ! Welcome to the family!

Channel your science anxiety into action. Comment on or before tomorrow! Keep scientists in roles at NIH and NSF and keep politicians out of them. Tell your non-science friends — universally hated idea to put politicians in these roles! 🧪

Come join us in Breckenridge, CO next May (2026) for the Beyond Antibiotics: Emerging Strategies for Combating Bacterial Infection

Short-term alterations in dietary amino acids override host genetic susceptibility and reveal mechanisms of Salmonella Typhimurium small intestine colonization In addition to individual genetics, environmental factors (e.g., dietary changes) may influence host susceptibility to gastrointestinal infection through unknown mechanisms. Herein, we developed a mod...

Can genetic resistance to Salmonella be impacted by dietary changes? We use a genetically resistant 🐭 to explore diet-microbiome-pathogen interactions and mechanisms of Salmonella Typhimurium small intestine colonization. Awesome work by grad student Nic Shealy!

As more information emerges about the firing of probationary employees from the NIH, it’s becoming clear how these actions are cruel and stupidly incompetent.
Why you might ask?

Were you fired by President Trump? | House Committee on Science, Space and Technology The House Committee on Science, Space and Technology

this website from the House Democrats on the Science, Space, and Technology Committee is surveying the impact of the Administration’s mass firings of federal employees from science agencies—share with friends you know have been affected

Dear federal scientists: If you have been affected by the probationary firings and would be willing to speak with Science, please reach out to me by email (klangin@aaas.org) or on Signal. We can guarantee annonymity.

Get in dorks, we're going protesting!

My student's diversity F31 has been pulled from study section even though it's the SAME APPLICATION as regular F31s, normally reviewed together in the same panel. Throwing out all the applications from URMs while the ones from white/privileged students get to be reviewed is blatant discrimination.

Also sharing the “Meet the Authors” highlight published with the review. Very proud of my amazing trainees Katerina Jones and Camila Brito for sharing a bit of their stories as the next generation of talented Latin Women in Science!
