Biography

I am a Postdoc in the EarthByte Group at the University of Sydney. I am interested in the inversion of thermochemical properties of the lithosphere subject to available geophysical data and their uncertainties. Inversions that couple multiple datasets ultimately improve the precision and understanding of the thermochemical evolution of the Earth.

I am passionate about open source software! On this website you will find links to repositories where source code is available with examples of how to reproduce peer-reviewed benchmarks and published results. You will also find code snippets that I have found useful - and maybe you will too!
