Postdoctoral Fellow 


I am interested in understanding how the host immune system maintains tolerance to commensal bacteria while defending against dangerous invaders, and how pathogens subvert this defense. I received my Ph.D. in microbiology, studying intestinal pathogenic bacteria. My current research examines resolution from intestinal inflammation in mouse models of colitis, focusing on host protective mechanisms that promote restoration of intestinal homeostasis.


Research Areas:


Th17 cells, intestinal restitution and repair, bacterial pathogenesis, intestinal microbiota.
