Sending signals

Linear polyubiquitin patches in the Salmonella Typhimurium ubiquitin coat, regulated by E3 ligase LUBAC and deubiquitinase OTULIN, serve as a platform to modulate xenophagy, NF-kB signalling, secretion of pro-inflammatory cytokines and bacterial proliferation. 

Refers to "Linear ubiquitination of cytosolic Salmonella Typhimurium activates NF-κB and restricts bacterial proliferation" by van Wijk et al. 

and 

"LUBAC-synthesized linear ubiquitin chains restrict cytosol-invading bacteria by activating autophagy and NF-κB" by Noad et al.

Associate Editor, Nature Microbiology

I first developed an interest in bacterial pathogenesis while at Cornell University. I then earned my PhD in Biomedical and Biological Sciences from Harvard University in Eric Rubin’s laboratory, studying cell wall remodelling in Mycobacterium tuberculosis. From 2012-2015, I continued my training as a postdoctoral fellow in Matthew Waldor’s lab at Harvard Medical School, investigating the role of DNA methylation on regulating fundamental cellular processes in Vibrio cholerae.
