Felipe Barbosa

Hey! I'm a Computer Science undergrad at Stanford University on the Artificial Intelligence Track, planning to graduate in June 2028.

I'm most interested in building the systems that let us simulate complex natural phenomena, from protein folding to the origins of life itself. I also spend a lot of time thinking about reinforcement learning, MDPs, and vision-language-action models for robotics.

Previously I led AI development at Onçafari, designed RAG pipelines and financial models at Atmos Capital, and researched molecular inhibitors at Stanford's Frydman Lab. This summer I'm joining Millennium Management as a Quantitative Research Intern.

Please reach out if any of these ideas sound interesting to you, and check out the other pages to learn more about me!

PolySolver
Monte Carlo Tree Search agent enhanced with action filtering, heuristic rollouts, and a domain-aware value function for The Battle of Polytopia. Achieves 100% win rate against all public baselines. A Deep Q-Learning agent trained on PolySolver trajectories recovers 60% win rate with no search at inference time.
