Lee is the Principal Research Fellow (Wildlife Biosecurity) and leads the One Health Research Group in the Faculty of Veterinary and Agricultural Sciences, University of Melbourne, and is interested in improving the health of humans, their animals and wildlife. His work has shown how their health is inextricably linked. Lee focuses on managing the spread and impact of emerging infectious diseases (EIDs) affecting all three groups, for which climate and globalisation have been major determinants. His work has shown that these drivers of EIDs across sectors require long-term, integrated solutions. The One Health approach offers efficiencies in understanding and solving these shared problems by involving multidisciplinary collaboration. Lee has held leadership roles within the Wildlife Disease Association, the Australian and New Zealand College of Veterinary Scientists and Wildlife Health Australia, and regularly provides advice to government and industry on wildlife health. Lee is the Regional Chair of the International Union for Conservation of Nature and the Species Survival Commission (IUCN/SSC) Wildlife Health Specialist Group for Australia – New Zealand and South Pacific.
