Air and metal pollution, bacterial infectious disease and antibiotic resistance.
Pollution and antimicrobial resistance are two of the major global challenges currently faced (World Health Organisation). Our research involves the elucidation of how bacteria adapt to air pollution and metal stress including anthropogenic metal pollution of the environment, and how this impacts bacterial survival in a host and in the environment, and drives antibiotic resistance.
Specific projects include investigation of:
- The impact of air pollutants on Staphylococcus aureus and Streptococcus pneumoniae colonisation and virulence.
- The role of bacteria in the detrimental health outcomes caused by high exposure to air pollutants in megacities.
- Environmental effects on host-bacteria interactions, and microbiomes.
- Impact of anthropogenic metal pollution on bacterial survival in the environment and co-selection for antibiotic resistance.
- The role of copper adaptive responses in bacterial colonisation, virulence and antibiotic resistance.
- The genetic mechanisms involved in persistent Staphylococcus aureus infections and antibiotic resistance.
- Investigation of a novel antibacterial target protein involved in antibiotic susceptibility of MRSA.
