Research Fellow, ETH AI Center and University of Zurich, Institute of Neuroinformatics

Previously, PhD candidate at the Champalimaud Centre for the Unknown in Lisbon under Joseph Paton

Bio

I work at the intersection of Mechanistic Interpretability and Cognition. I'm interested in how biological and artificial systems learn internal representations of the world through action and inference. My work combines computational neuroscience, reinforcement learning, and latent-state modeling to understand decision-making, reasoning, and adaptive behavior. I am currently in the labs of Valerio Mante and Benjamin Grewe. If you're interested in working with me, please check the Projects page.
