Research Interests

Using nucleic acid amplification technology for detection of Chlamydia pneumoniae, Chlamydia-like organisms and other respiratory pathogens (M. tuberculosis, S. pneumoniae, Legionella spp., M. pneumoniae) in clinical specimens from patients with respiratory disease.

Using nucleic acid amplification and rapid DNA sequencing technology for typing, identifying, and characterising infectious agents that may impact on the onset or progression of chronic diseases such as COPD and cardiovascular disease.

Optimization of molecular diagnostics for use in the clinical microbiology laboratory and evaluation of their impact on patient care.
