My research falls in three sections. The first between 1965 and 1983 was concerned largely with influenza, with emphasis on virus genetics, live virus vaccines, and the ecology of avian influenza in wild birds in Western Australia. During this phase, studies were also undertaken with foot-and-mouth disease virus, avian paramyxoviruses and murine cytomegalovirus. The second phase from 1983 to the present has been concerned with mosquito-borne viruses, including Ross River, Barmah Forest, Murray Valley encephalitis, West Nile and Japanese encephalitis viruses. The emphasis has been broad and has included surveillance, virus ecology, molecular biology and phylogenetics, diagnostic developments, and host resistance. The third phase has been in two parts – one concerned with emerging zoonotics bat-borne diseases including Hendra virus and Australian Bat lyssavirus, and the other concerned with global surveillance and response activities for infectious diseases.
