The CED is a reference centre in South Africa for human isolates of Salmonella species, Shigella species, Campylobacter species, Vibrio cholerae, Listeria monocytogenes and diarrhoeagenic Escherichia coli. My current activities include diagnosis, surveillance and epidemiology of enteric bacterial pathogens in South Africa. I lecture and teach on the application of molecular techniques in the microbiology laboratory, including techniques related to laboratory identification and characterization of bacterial enteric pathogens. These techniques include PCR, molecular subtyping of bacteria (PFGE, MLVA and MLST), whole-genome sequencing (WGS) and metagenomics. I am also involved with supervision of post-graduate students and training of intern medical scientists. My supervision of post-graduate students includes 6 PhD students and 14 MSc students. My publication record includes 98 peer-reviewed publications. Most of my published work can be found at the following links: https://www.ncbi.nlm.nih.gov/myncbi/1vGRCoG6Yfq/bibliography/public/(external link) OR https://scholar.google.co.za/citations?hl=en&user=D_v5biMAAAAJ&view_op=list_works&sortby=pubdate(external link).
