Background

Romesh joined Burnet at the start of 2018 to work on Optima TB and HCV modelling. He completed his undergraduate studies and PhD in Physics at the University of Sydney. After working on software development for the Optima HIV project in 2015, he took up a postdoctoral research position at the Oxford Centre for Human Brain Activity where he worked on biophysical modelling of neural activity.

Now back in Australia, Romesh is based in Sydney. His research interests include quantitative predictive modelling and optimization, with a particular focus on data-driven model validation. He is currently also working on COVASIM: Modelling COVID-19 - an individual-based model assessing the impact of COVID-19 interventions that has informed the Victorian Government’s Roadmap through the COVID-19 pandemic.
