Michael Walsh is an infectious disease 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 human and animal pathogens and their interaction with hosts, vectors, and environments in shaping landscape risk. As such, he explores complex etiologies using 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 endemic and emerging zoonotic infections, and the ways in which interactions among wild and domesticated animals in anthropogenically altered landscapes enhance the potential for pathogen spillover from primary reservoir hosts to novel hosts. Michael has 18 years’ experience as an epidemiologist and is currently investigating the landscape epidemiology of both Hendra virus and Ross River virus. Michael has taught infectious disease epidemiology and epidemiologic methods for over 13 years on the faculty of New York University; the State University of New York, Downstate; and the University of Sydney.
