Biography

Hola!

I’m Ana, a chemical engineer-turned-volcanologist, who's passionate about studying Earth's most amazing features. I do so via in-situ and remote observations, as well as through designing and conducting experiments in the lab. My research has focused on the reactions of volatiles (S, Cl) within rocks, glasses and ah in volcanic settings, which are still poorly understood.

Here at ANU, I aim to unravel the kinetics of reactions between SO2 gas and rock-forming minerals (e.g. pyroxenes), by combining novel experimental, analytical and modelling work. This research is not only exciting(!) but also relevant from various points of view; reactions between sulphur-gases and minerals are key agents for the re-distribution of sulphur on earth and planetary systems, thus are important to better understand ore-deposit formation processes and to gain accuracy in estimating sulphur budgets during volcanic eruptions and in geochemical cycles.

Besides science, I'm passionate about running and Anzac bikkies.
