The Biogeography, Ecology and Modelling Lab at the University of Technology Sydney, in collaboration with the Australian Museum, is seeking Expressions of Interest for a postdoctoral research opportunity. The project, led by Dr Frédérik Saltré and colleagues, focuses on forecasting climate-driven scrub typhus risk in Australia. This interdisciplinary research aims to develop mechanistic models of vector ecology and disease risk under current and future climate scenarios, integrating population ecology, disease epidemiology, and climate science. The successful applicant will work on quantifying age-structured population dynamics of the chigger mite Leptotrombidium spp., the primary vector of scrub typhus, using species distribution and Leslie matrix models. The project will also incorporate ecological niche models for both the mites and their rodent hosts, such as Rattus rattus, and demographic modelling to better understand host–vector interactions and disease transmission dynamics. The research objectives include identifying climate-sensitive bottlenecks in the chigger mite lifecycle, predicting spatiotemporal risk of scrub typhus outbreaks, and informing targeted vector control and climate-responsive disease management strategies. Eligibility criteria require applicants to be Australian citizens, permanent residents, or New Zealand Special Category Visa holders, and to have a PhD in applied mathematics, numerical modelling, climate science, computer science, or related fields awarded within the past 10 years. Strong programming and modelling skills, a proven research track record, and excellent communication abilities are essential. The position is based at the University of Technology Sydney, with mentorship from Dr Frédérik Saltré (UTS/Australian Museum), Prof Shane Ahyong, Dr Matt Shaw, and Dr David Alquezar (Australian Museum). The opportunity is supported by the National Intelligence Postdoctoral Grant, which provides $365,000 over two years. This is not a direct job offer; rather, selected candidates will co-develop a competitive funding application for the grant. The deadline for submitting an Expression of Interest is 6 January 2026. Applicants should use the provided form, address all eligibility criteria, upload a CV, and provide contact details for two academic referees. Shortlisted candidates will be contacted shortly after the deadline, and the successful applicant will be supported through the full proposal preparation process.
