I am a third year ETH AI Center Doctoral fellow, supervised by Prof. Konrad Schindler (ETH, PRS) and Prof. Jan Dirk Wegner (UZH, Ecovision). My research lies at the frontier of computer vision and remote sensing to solve scientific questions in the environmental sciences. In particular, my current work focuses on high-resolution global mapping of above-ground biomass.

I am also the co-founder and an active member of the AI + Environment Summit, a non-profit that organizes the eponymous event.

I did my MSc at ETH Zurich, and my undergrad at École Polytechnique (Paris).

To address the spatially structured residuals and biases typical of large-scale AGB products, we develop a post-hoc calibration scheme using Gaussian Process Regression.
