I am a geochemist researching how chemical weathering—the breakdown of rocks through reactions with water, oxygen, and various chemical and biological agents—affects Earth’s climate and habitability by consuming or releasing greenhouse gases and providing essential nutrients for life.
My work combines laboratory experiments and fieldwork to explore these surface processes in depth. Recently, I completed my PhD at the University of Cambridge, where I studied how ion-exchange reactions between sediment surfaces and water can influence our understanding of chemical weathering by altering the chemical composition of ground and river water. To investigate these processes, I used a range of tools, including stable and radiogenic isotopic tracers, with a particular focus on stable barium isotopes.
Currently, I am studying the climate impact of deglaciation—the melting and retreat of glaciers driven by rising temperatures. My research examines how the exposure of previously buried geological carbon stores to oxygen, as glaciers recede, can release CO₂. These processes may have hidden positive feedbacks that could intensify current climate change. To better understand these dynamics and their implications, I conduct laboratory experiments and fieldwork in the Arctic.
