Audrey MARGIRIER

I am fascinated by the interactions between geodynamics, tectonics, climate, and surface processes and more specifically in their contribution to the evolution of the landscape at different timescales from tens of millions of years to a thousand years. To address these issues, I use a multidisciplinary approach combining geology with thermochronological analyses, 10Be and OSL dating, and numerical models and I have been working with collaborators from various fields including tectonics, noble gas geochemistry, petrology, terrestrial cosmogenic nuclides, and surface processes modelling. My research established the role of deep-seated processes in the structural and topographic evolution in the Andes. My recent work demonstrated the positive retroactions between erosion and tectonics and evidenced the importance of changes in climate on denudation and landscape evolution.

I am currently working at the University of Lausanne.
