Associate Professor/Reader
School of Animal and Veterinary Science
Faculty of Sciences, Engineering and Technology
I am a founding member of the Parasitic Diseases Research Group (ParaDRG) at the University of Adelaide. My research interests and expertise is focused on the biology and control of parasitic diseases. I am specifically interested in the development of vaccines and novel drugs to control parasitic diseases in livestock and companion animals. My current research is targeted to apicomplexam parasites such as Toxoplasma gondii and eneteric coccidia, but I am also interested in Giardiasis, gastrointestinal nematodes and canine heartworm.
I also have a keen interest in parasite diagnostics and lead the Parasitology section of the Veterinary Diagnostic Laboratory at the School of Animal and Veterinary Sciences.
