Biography
After completing undergraduate degrees in Computer Science and Engineering, and a MPhil in Computer Science, Rhys worked for more than a decade as a research programmer with positions at the ANU School of Computing, CSIRO, and NCI (Australia’s peak supercomputing facility). He developed an interest in the Earth sciences which lead to him completing a PhD in Geophysics in 2018. Rhys combines computational geophysics, applied mathematics and machine learning techniques to robustly determine the composition of the Earth at various scales
