We study the neural control of complex, coordinated behavior. The lab builds machine-learning models of neural activity and behavior that are constrained by anatomy and physiology — using these models to predictively understand how the brain produces movement and how behavioral structure emerges from neural dynamics.

- Embodied sensorimotor control. Anatomically-accurate musculoskeletal models of monkey and mouse, driven by RNNs trained with deep reinforcement learning, to ask how the motor system produces goal-directed behavior.
- Neural dynamics & state-space modeling. Switching, time-varying, and multi-regional recurrent networks for inferring latent dynamics from neural recordings.
- Multimodal behavioral representations. Autoencoders and variational methods for disentangling shared structure across neural activity, video, and behavior — across subjects and across modalities.
