- Research Disciplines
Australia's foremost aquatic animal disease specialist. Instigated the study of bacteriophage at James Cook University. Most interested in bacteriophage in the Vibrio harveyi clade and viruses of crustacea especially the parvoviruses and the use of RNA interference to combat them. Interested in nodaviruses of fish and crustacea and RNA intererference as a control. Investigating the role of viral UTRs in controlling immunity and diabetes onset.

Viral Causes of Crayfish Handling Mortalities
- Indicative Funding
- $40,000 over 3 years (administered by North Queensland Crayfish Farmers Assn)
- Summary
- Northern Queensland crayfish from farms affected by stress, particularly transportation stress, started to die with mortality reaching 20-40% after about three weeks. Two new viruses were found, Cheque iflavirus and Athtab Bunya-like virus. This research will determine the infection cycle of the viruses to understand how to intervene and control the impact of these viruses.
