I am a post-doctoral Earth Scientist at the University of Lausanne working on skarn deposit formation processes. My interests include electron microscopy, crystallography and mineralogy, and material chemistry.

Outside of work, I enjoy gardening, cooking, and reading next to my cat. I enjoy long hikes in the forest identifying fungi and taking care of my exotic orchid collection.
