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



My research currently encompasses three main areas:

1) determining the past size of ice sheets and associated contribution to sea-level change;

2) investigating the drivers and mechanisms of ice sheet behaviour; and

3) developing the applications of cosmogenic nuclides and surface-exposure dating.

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, videos, news articles, and was co-founder of Climatica – a climate science-public interaction initiative.


We studied how the Antarctic ice sheet advanced and retreated over 10,000 years. It holds warnings for the future, The Conversation (July 2022).
