Dr Rachel Sacks-Davis is an Early Career Research Fellow at the Burnet Institute in the Disease Elimination Program.
Recently she has been working on a COVID-19 epidemic model, looking at diagnostics and screening.
After completing her BA (Hons)/BSc Rachel joined Burnet as a Research Assistant in 2008. Since then she has worked on a range of projects in sexual health and blood-borne virus epidemiology.
Rachel’s PhD combined epidemiology, phylogenetics, social network analysis and mathematical modelling to study hepatitis C transmission and natural history amongst people who inject drugs. In 2015 she will be commencing an Early Career Fellowship using mathematical modelling to study tuberculosis and other infectious diseases.
