We are also excited to welcome a new postdoc @jrlane2014.bsky.social to the Rosen Lab! We hope she likes Klebsiella pneumoniae as much as Streptococcus pneumoniae. Fun fact: Jessica has 2 cats named Teddy and Binx 🐈 🐈⬛

I hope that it is a helpful overview of the connections between the preterm gut microbiome and disease. It's the Schwartz lab's first review and summarizes our group's major focus
