About

I am a physicist and AI scientist with a background in high-energy particle physics and a passion for applying machine learning to complex, data-rich problems. My research spans jet physics at the ATLAS experiment, graph neural networks, and quantitative finance.

I enjoy building tools at the intersection of physics intuition and modern deep-learning architectures — from LundNet jet taggers to GNNs in Julia. When not crunching collider data, I explore algorithmic trading strategies and write about things I find interesting.
