Research focus and collaborations

My research interests are in the role of transition metal ions and redox processes in biology. The main focus of our research is bacterial pathogens, principally Streptococcus pneumoniae, Neisseria gonorrhoeae, Haemophilus influenzae and enteric bacteria. This research also involves investigation of the interaction between bacterial pathogens and the host innate immune system.

Current research projects include:

  • the biochemical mechanism of action of the novel thiol-based sensor NmlR and its role in the regulation of the response to nitrosative and carbonyl stress in bacterial pathogens
  • interplay between manganese, iron and zinc in the control of the virulence of pneumococcus
  • trafficking of copper and iron in macrophages in response to bacterial pathogens
  • adaptation of the respiratory chains of bacterial pathogens in response to metal ion and carbon source availability.
