I'm a master's student in Neural Systems and Computation at ETH Zürich and the University of Zürich, with a BSc in Cognitive Science from Aarhus University. My work sits at the intersection of Bayesian statistics, AI, computational neuroscience, and Active Inference, where I build and fit mathematical models of how minds infer and act in the world.

Since January 2025, I've been a software developer at the Theoretical Neurobiology Unit (TNU) at ETH Zürich, where I co-authored and help maintain ActiveInference.jl, a Julia library for simulation and parameter estimation of Active Inference models.

Outside of research, I read broadly in philosophy of science and existential philosophy, play guitar, and rarely turn down a board game.
