Research

1. Understanding the link between microbial metabolism and virulence. Particular topics, I study include:

  • The pneumococcal mechanisms to acquire host sugars,
  • Regulation of sugar metabolism in Streptococcus pneumoniae.

2. Study of the pathways involved in microbial oxidative stress resistance

  • Characterisation of enzymes that have a role in detoxification of reactive oxygen species,
  • Understanding the regulation of oxidative stress resistance in bacteria.

Methods used: I use a wide range of bacteriology, molecular biology, cell culture techniques, as well as in vivo models of microbial diseases.

Supervision

Topics available for supervision

The impact of in vivo derived sugars on bacterial physiology and virulence.

Oxidative stress response of pathogenic bacteria.
