Overview

I am an experienced microbiologist with a strong passion for investigating the molecular basis of infection caused by bacterial pathogens. My current research focuses on pathogenic Vibrio species, how they survive in the environment, and how they cause disease in humans. I am interested in understanding what governs how bacterial species wake up and grow in the natural environment after a period of long-term dormancy.
