Clostridium difficile • healthcare-associated infections • infection control

Research Interests

My research focuses on healthcare-associated infections and I have a particular interest in Clostridium difficile infections (CDI) . My research examines the epidemiology of CDI, looking at risk factors for infection and colonization as well as different strategies for prevention of transmssion. I am also involved in the evaluation of rapid diagnostic tests for CDI.
