My background is in earth and environmental sciences, with particular focus on the interaction between ice and climate.

Science. My research currently encompasses three main areas: 1) investigating the dynamic response of Antarctic outlet glaciers during retreat; 2) determining how the size of the Antarctic ice sheet has changed in the past, and estimating the associated contribution to sea level; and 3) developing the applications of cosmogenic nuclides and surface-exposure dating to better reconstruct ice sheet history.

Outreach. I am passionate about engaging the wider public in Antarctica and climate-related science. In particular, I share my Antarctic experiences through an online blog and videos, and was co-founder of Climatica – a climate science-public interaction initiative, which offers short articles about climate change and the Earth system, written by relevant scientific experts.
