Research Interests:

Management of microbial biofilms in water systems in healthcare facilities.

One of my main research interests focuses on the development of automated systems for controlling microbial contamination in water systems in healthcare facilities, especially those supplying medical devices such as dental chair units. Waterborne spread of infectious disease is potentially significant with medical devices supplied with water. This research is fundamentally translational and involves industrial partners in Finland (Planmeca) and in Ireland (Trustwater) and has resulted in the development of novel dental chairs with automated and semi-automated control systems for eliminating microbial contamination. Large-scale automated systems for maintaining the water quality in large water distribution systems at better than drinking quality have also be developed and successfully commercialised. Current work includes the application of Trustwater Ecasol vapour technology for the rapid and effective environmental decontamination of healthcare facilities.

Molecular epidemiology and population analysis of MRSA.

Another main research interest concerns the population analysis of MRSA from hospital and community sources. MRSA have been endemic in Irish hospitals for nearly 40 years and have been responsible for considerable patient morbidity. The recent emergence of community-acquired MRSA has added to this problem. Infections with MRSA also cause a considerable drain on limited healthcare resources. My work in this field focuses on high-throughput screening of populations of MRSA using sophisticated DNA typing systems and DNA arrays. This allows the accurate tracing of the sources of MRSA and allows the early identification of emerging strains with enhanced virulence potential and antimicrobial agent resistance.

Epidemiology and population biology of Candida dubliniensis.

Candida dubliniensis is a pathogenic yeast species discovered by Derek Sullivan and I in 1995. The organism causes infections in immunocompromised and debilitated patients. My research on this yeast focuses on its epidemiology, population biology and drug resistance mechanisms, work that is complementary to research undertaken by other members of the Microbiology Unit.
