David Goll

Physicist passionate about RL

About

I am a Reinforcement Learning (RL) enthusiast, fascinated by how intelligent behaviour can emerge from simple interaction rules.

Trained as a physicist, specialised in statistical physics and modelling of complex systems, I enjoy applying analytical tools to study emergent phenomena. In my Master’s thesis, I studied the learning dynamics of Multi-Agent Reinforcement Learning, uncovering rich and unexpected behaviours even in minimal systems.

I am now seeking opportunities to apply my expertise in various fields, where I can combine my strong quantitative background with my interest in machine learning.
