Our main research interests focus on the ubiquitous bacteria Salmonella enterica, its interactions with the host and the ways this pathogen causes diseases. Current projects in the lab include the following subjects:


1. Why and how different Salmonella enterica serovars are differ in host-specificity and clinical outcome?


2. Virulence regulation in Salmonella and its response to environmental signals.


3. Mechanisms of population dynamics and changes in serovars prevalence at the national level.


4. The biology of invasive and persistent Salmonella infections.
