I had two grant proposals up for review in the NIH Bacterial Virulence (BV) study section. It was canceled without notice this morning.
Without those grants, my lab must close within a year.
And so the purge of scientific research in the US continues

ASM did a spotlight article on me last February and it has also been taken down as “under review”. Other spotlight articles are still up so not sure how else to interpret this besides the obvious. It feels pretty crappy to have been singled out and I won’t be engaging with them in the future.
I want to expand on the extent to which IDEAA materials have been purged: I wrote an article last year for women’s history month on the history of women in antimicrobial development….DELETED.
I’m on one of ASMs IDEAA committees and we have received 0 communication from ASM staff on why this is happening. I had to find out via social media. Extremely disappointing.

I am excited to announce our latest publication! We teamed up with @khullahalli.bsky.social to barcode Klebsiella and ask basic questions about bacteremia pathogenesis: 1) how are bacteria shared between sites and 2) which host and bacterial factors influence dynamics?

New commentary!🦠In this mSphere of Influence article, I talk about my fascination with host-pathogen interactions during systemic infection and highlight two studies that have been significant in developing this interest.
