Research interests

Interests in food- and water-borne pathogens and their relationships between fitness and virulence.  Focus on Legionella pneumophila, (waterborne, cause of Legionnaires’ Disease) particularly on (i) the mature infectious form (MIF) believed to be its natural transmissive form; (ii) surface-associated Legionella chaperonin and its effects on eukaryotic cells.
