Research Interests

  • Plant viruses
    Associate Professor John Thomas is a plant virologist, based at the Ecosciences Precinct at Dutton Park. His research focuses on the identification and control of plant virus diseases, especially those affecting tropical and sub-tropical crops. These aims are achieved through molecular characterisation of viruses and the development of diagnostic assays, epidemiological studies and collaborations with plant breeders and tissue culture specialists.
