Research interests

The discovery of penicillin by Sir Alexander Fleming heralded the beginning of the Antibiotic Era, offering hope for the treatment of many infectious diseases. However, within just a few decades, the emergence of "superbugs" with resistance to multiple classes of antimicrobial agents threatens to bring it to an abrupt end. The widespread use of antimicrobial agents is one of the main drivers of the development of antimicrobial resistance in human pathogens. Antimicrobials are used not only in human and veterinary medicine, but also in animal husbandry and other agricultural activities and are increasingly being used in surface wipes and other products used for domestic cleaning and personal hygiene. I am currently investigating the emergence and epidemiology of microbes that are resistant to multiple antimicrobial drugs, in particular hospital and community acquired methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci.

Teaching and supervision

I deliver lectures and small group tutorials and practical classes to undergraduate and graduate entry masters students on the Cumberland Campus. My main teaching areas are introductory microbiology, infectious diseases including emerging infectious diseases, infection control, introductory human cell biology and human musculoskeletal and body systems anatomy.
