Professional biography

Currently, I am a PhD student within AstrobiologyOU and my project focuses on the signatures of salty ices forming in the plume environment at ocean worlds like Enceladus. I will be exploring the freezing process of salt-rich ices that are considered to best represent the ocean composition. This can help inform our understanding of how ocean material is transferred into the plume, and will thus help inform our interpretation of plume ejecta observed remotely by spacecraft. I have conducted vacuum chamber experiments to simulate the low pressure environments that such ice grains form in, to quantify the freezing behaviour, which I will then link to various compositional analyses.
