BIO

  • Received her PhD in Biochemistry and Molecular Genetics from the University of New South Wales, Australia, studying novel metabolic pathways in the protozoan parasite, Giardia lamblia.
  • For postdoctoral research she studied developmental gene regulation in Giardia lamblia at the University of California, San Diego and Salmonella enterica-host interactions at the University of British Columbia, Canada.
  • Transitioned to a Staff Scientist position at the Rocky Mountain Laboratories, NIAID, NIH studying Salmonella-host cell interactions.
  • Started own research group at Washington State University in 2012. She received tenure and promotion to Associate Professor in 2019.

Salmonella-Intestinal Epithelial Cell Interactions

Research in our lab focuses on gastrointestinal diseases. We aim to understand how pathogenic bacteria colonize the gut, proliferate and spread. These confocal microscopy images show Salmonella enterica replicating in different intracellular compartments in intestinal epithelial cells.
