Research Interests

  • Ecology and molecular biology of bacteriophages and their relationships with bacterial hosts; ranging from bacterial pathogens to environmentally important cyanobacteria.
  • Exploitation of bacteriophages and phage-derived products as an alternative to treating antibiotic resistant bacterial infections e.g Clostridum difficle infections.
  • Sequencing and annotation of newly isolated cyanophages. Establishing the function of key cyanophage genes to link gene function to ecology of the organisms and investigation the potential to exploit unique enzymes found in cynophage genomes.
