Representation learning & sequential decisions

Research

My work in reinforcement learning studies how policy structure and observation representations affect learning in coupled systems. I also contribute to research on recurrent-agent behavior and language-model evaluation.

Current research

Representation learning, coordination and model behavior.

Earlier work

Thesis research and collaborative work at RWTH Aachen.

Presenting at MIT

I presented my work on multi-agent reinforcement learning at MITEI's Annual Research Conference, discussing graph representations and the coordination of local policies.
