Honorary Research Associate
BSc DPhil
Dr Shearer is an NHMRC Research Fellow based at The University of Melbourne. Her expertise is in the use of data analytics, modelling, and decision science to support infectious disease management. Her work focuses on two broad pathogen types: those with constrained geographic distributions due to their complex transmission cycles involving multiple animal reservoir and vector species (e.g., zoonotic malaria); and those of pandemic potential due to their novelty and direct/efficient human-to-human transmission (e.g., SARS-CoV-2).
Since January 2020, Dr Shearer has been engaged in supporting the Australian Government response to COVID-19. She has a leadership role in weekly reporting to key national decision-making committees on state-level and national epidemic situational assessment.

Updating estimates of Plasmodium knowlesi malaria risk in response to changing land use patterns across Southeast Asia
Plasmodium knowlesi is a zoonotic parasite that causes malaria in humans. The pathogen has a natural host reservoir in certain macaque species and is transmitted to humans via mosquitoes of the Anopheles Leucosphyrus Group. The risk of human P. knowlesi infection varies across Southeast Asia and is dependent upon environmental factors.

The ability for vaccines to protect against infectious diseases varies among individuals, but computational models employed to inform policy typically do not account for this variation. Here we examine this issue: we implement a model of vaccine efficacy developed in the context of SARS-CoV-2 in order to evaluate the general implications of modelling correlates of protection on the individual level.
