Excited to share my latest postdoctoral work in the Shen Lab at Tufts! In this study, we follow up on an exciting finding by former grad student @shailab.bsky.social that C diff uses its Class A PBP (PBP1) to drive cell division (unlike previously studied bacteria)! journals.plos.org/plosgenetics...
Molecular dissection of Class A PBP function uncovers novel features of the non-canonical Clostridioides difficile divisome complex
Author summary Bacterial cell division is an ancient and essential process, but our molecular understanding of this process is primarily based on studies in a select few model systems. Recent work fou...

Check out our new paper: a review of translational coupling, the phenomenon where translation of one prokaryotic gene can promote translation of the gene downstream. We cover the history, and delve into the mechanism, which is still not fully understood. journals.asm.org/doi/10.1128/...
Translational coupling of neighboring genes in prokaryotes | Journal of Bacteriology
Prokaryotic genes are arranged in operons, with functionally related genes often located adjacent to one another (1). There are several ways in which the operonic organization of genes facilitates the...

I'm pleased to announce that I will be starting my lab as an Assistant Professor at UMass Chan Medical School in August! My group will study phages that infect corynebacteria and mycobacteria to understand bacterial cell envelope assembly and phage gene function. Website and more info to come soon!
