My research interests include diagnostic test evaluation and development for the detection of microbial pathogens in clinical specimens. Recent projects have included:use of 16S rDNA-sequencing for identification of non-tuberculous Mycobacteria; evaluation of molecular strain typing techniques for epidemiological analysis; development of molecular and non-molecular assays for rapid identification and susceptibility testing of MRSA; evaluation of methods for Clostridium difficile detection
