Biography
I am a geomorphologist working across disciplines to interrogate the impact of climate change on the evolution of mountain landscapes and their rural communities. My research is currently focused on Chile and understanding how climate drives the movement of sediment along semi-arid mountain rivers. My interest is on the role of extreme weather events in intiating and propogating hazardous sediment cascades through mountain ranges and downstream, into populated areas.
Throughout my research I have been examining the impact of climate on the Andes of Chile and Argentina across different time scales through combining field data with statistical and numerical modelling. This has included an exploration of:
- How climate and tectonic signals are preserved in sedimentary records
- How postglacial catchments evolve under spatial variability in climate
- How climate modulates the building of Andean topography
- How extreme climate events contribute to the evolution of sediment routing systems and the cascading of sediment hazards
I also have an ongoing interest in engaging with decolonial scholarship and the critical geographies that explore alternate knowledges of human-landscape relationships. I am working with rural communties in Chile to develop knowledges and tools that can support the creation of disaster risk reduction strategies that are inclusive and focused on the long term management of climate change impacts. Enquiries of any form are welcome!

In the nearby town of Los Queñes, local residents evacuated their homes as torrents eroded away houses and sections of road. Many were left isolated and without access to basic services.
