Biography/ Background

Course coordinator for Classical Diagnostic Methods in Plant Health and Molecular and Biochemical Diagnostic Methods in Plant Health, which is part of the Postgraduate Training in Plant Health.

Research Interests

  • Determining the cause of virus-like diseases (examples include Mundulla Yellows of Eucalyptus, chlorotic streak disease of sugarcane, and orange spotting of oil palms),
  • The characterisation of viruses and viroids, diagnosis by serological and nucleic acid based assays,
  • Studies of interactions between viruses and vectors, the epidemiology of viruses and the development of cultural control methods,
  • Cloning and sequencing of virus genomes,
  • The introduction of virus genes into plants to induce transgenic resistance,
  • The analysis of geminivirus DNA replication.
