I am a postdoctoral researcher in the Alpine Mass Movements group of ETH Zürich and the Swiss Federal Institute for Snow and Avalanche Research (SLF) in Davos. In 2023, I defended my PhD in Mechanics at EPFL, supervised by Prof. J. Gaume and Prof. J.-F. Molinari. My research focuses on computational modeling of the mechanics of porous solids and granular flows, with a particular emphasis on snow. I’m currently working with the Material Point Method (MPM), however, I am interested in the development and application of all kinds of numerical methods in solid and fluid mechanics.

Previously, I have worked for DNV Oil&Gas, EVRY Consulting and interned at FFI and Equinor. I received a Master of Science in Computational Science and Engineering from ETH Zürich in 2018, with the thesis entitled Computing Measure-Valued Solutions of the Leray-Alpha Model of Turbulence supervised by Prof. S. Mishra at the Seminar for Applied Mathematics.
