If you had told Samuel Hinton six months ago that he would be spending half his working hours crunching corona data, he would probably have assumed you were talking about the plasma aura around some star.

Instead, the University of Queensland astrophysicist is leading a project to synthesise data on Covid-19 patients from 48 countries.

鈥淭he skills that you get from astrophysics 鈥 it turns out they鈥檙e fairly translatable,鈥 Dr Hinton said. 鈥淚n astrophysics we get raw, messy data that we can鈥檛 use from a telescope. We鈥ake this data, homogenise it, process it [and] store it somewhere [so that] we can actually make use of it.

鈥淚t鈥檚 the same in the Covid collaboration. We take raw, messy data 鈥 but instead of from a telescope, we take it from hospitals. You swap the telescope [for] 350 hospitals and hope you can get something of value.鈥

As lead data analyst for the Covid-19 Critical Care Consortium, Dr Hinton has constructed what the Australian Academy of Science refers to as a 鈥渄ata science pipeline鈥. It ingests raw clinical data from around the world and processes it into a usable form for machine learning and statistical analysis.

Dr Hinton also built and maintained an 鈥渋nteractive dashboard鈥 which aggregates the data and provides snapshot summaries for clinical teams. 鈥淵ou could say: 鈥榃hat is the chance that a person would develop this complication, whether they鈥檙e male or female, whether they come from the US or not?鈥欌

The pandemic has bowled up new surprises for Dr Hinton, who was a contestant in the reality TV show聽Australian Survivor聽during his doctoral studies in 2018. Early this year he accepted a Chamberlain postdoctoral fellowship with the Lawrence Berkeley National Laboratory in the US. 鈥淚鈥檓 supposed to be there pretty soon, but obviously that isn鈥檛 happening.鈥

He聽got married in April and spent his wedding night plotting data for clinical staff at the Prince Charles Hospital in Brisbane. 鈥淲e were having the global consortium meeting the next night and needed the plots done.鈥

The Academy has highlighted Dr Hinton鈥檚 efforts as an example of the unexpected spin-offs from Australia鈥檚 research strength in astronomy. A聽聽of Australia鈥檚 10-year plan for the discipline, overseen by the Academy鈥檚 National Committee for Astronomy, has found that Australia鈥檚 optical and radio observatories 鈥 currently among the world鈥檚 best 鈥 have fostered the application of advanced data analytics in completely unrelated fields.

Other by-products have included technologies that boost the output of solar farms, improve situational awareness and reduce vibrations in harsh environments.

Meanwhile, Australian researchers have played their part in some of the biggest astronomical discoveries of the past decade. They include the detection of gravitational waves and the use of mysterious 鈥渇ast radio bursts鈥 to find the universe鈥檚 鈥溾 floating around in interstellar space.

Review panel member Tamara Davis said that Australia had a natural advantage in astronomy research 鈥渂ecause of our radio-quiet skies and important southern hemisphere location. Many countries want to be involved in telescopes in Australia.鈥

The review offers nine recommendations to consolidate Australia鈥檚 standing in the field. They include completing Australia鈥檚 component of the Square Kilometre Array radio observatory, funding Australian-built instrumentation for the Giant Magellan Telescope in Chile, laying the foundations for a gravitational wave detector in the southern hemisphere, and achieving full membership of the European Southern Observatory.
