Biographical details

Michael Walsh is a landscape epidemiologist with the Marie Bashir Institute for Infectious Diseases and Biosecurity at the Westmead Institute for Medical Research. He is interested in the complex ecologies of zoonotic pathogens and their interaction with hosts, vectors, and environments to shape risk. As such, he applies methods from traditional spatial epidemiology, as well as more modern applications of biogeography, ecology and data science to inform infectious disease inference and prediction. Michael is particularly interested in the ways in which interactions among wild and domesticated animals in anthropogenically altered landscapes facilitate pathogen spillover from primary reservoir hosts to novel hosts. Michael has 19 years’ experience as an epidemiologist and is currently investigating the landscape epidemiology of Ross River virus and zoonotic pathogens in pastoralist communities. Michael has taught infectious disease epidemiology and epidemiologic methods for 14 years on the faculties of New York University, the State University of New York, Downstate, and, currently, at the University of Sydney.
