Michael Walsh is a landscape epidemiologist with the Sydney School of Public Health and the Sydney Infectious Diseases Institute. He is interested in the complex ecologies of zoonotic pathogens and their specific interactions with hosts, vectors, and environments to shape risk. As such, he combines methods from spatial and infectious disease epidemiology with applications of biogeography, community ecology, functional ecology, and landscape ecology to employ transdisciplinary One Health approaches to zoonosis inference, prediction, surveillance, and prevention. Michael is particularly interested in the ways in which interactions between wildlife, domesticated animals, and humans in anthropogenic landscapes facilitate pathogen spillover from primary reservoir hosts to novel hosts.
