  • Plant-microbe interactions 
  • Plant pathology
  • Microbial ecology
  • Bio-fertilisers
  • Sustainable soils


To utilise a multi-disciplinary approach to understand the interaction of micro-organisms with plants and their environment. Investigating epidemiology, population structure, pathogenesis and control strategies for plant pathogens. Population structure, efficacy and interaction of beneficial micro-organisms with plant pathogens and soil. Plant-microbe interactions in both agricultural and native ecosystems.
