Dr Conor P O'Byrne

Director
Bacterial Stress Response Group

The research focus in my group is on the molecular mechanisms that food-borne bacterial pathogens use to sense and respond to harsh conditions in their environment. Pathogens encounter major physicochemical changes as they transition from food into the host, particularly in relation to pH, osmolarity, oxygen concentration, light and temperature.
