After studies in veterinary science, Lee pursued a career in wildlife health research. He later undertook a Bachelor of Animal Science on parasites of native animals with Ian Beveridge. After a sojourn in mixed clinical practice in rural Victoria Lee returned to research studying Australian bat lyssavirus and lead poisoning in flying foxes before undertaking a PhD on sarcoptic mange in wombats, followed by a postdoc on diseases of sea ducks at the USGS National Wildlife Health Centre in Madison, Wisconsin. On returning to Australia Lee established a One Health Research Group studying diseases impacting biodiversity such as chytridiomycosis and important emerging zoonoses like avian influenza and Hendra virus.
After studying wildlife health parasitology Lee has added virology, toxicology and microbiology. He joined the epidemiology chapter of the ANZCVSc, as he is mainly interested in controlling wildlife diseases to improve conservation and health outcomes. Lee is a Principal Research Fellow in Wildlife Biosecurity at the University of Melbourne.
