Pyrros Nikias Koussios

I am an M.Sc. student in Electrical Engineering at ETH Zurich, currently at Stanford University working on my master's thesis with Prof. Dorsa Sadigh and Prof. Chelsea Finn. My research interests are broadly in policy learning, reinforcement learning, and robotics, particularly in how strong priors from large-scale pretraining can be leveraged to learn more general, efficient, and reliable policies.

I previously worked with the DISCO and LAS groups at ETH Zurich on representation learning for downstream pixel-based RL and on adapting VLMs as reward models for RL. I have also worked as an LLM Research Assistant at Oracle Labs.
