Research Interests:

Modern neuroscience sees the brain as an information-processing device. Understanding how the brain processes information requires understanding the representations used by the network of neurons that compose the brain. However, representations in the brain are distributed: each cell carries only a small portion of the total information. I am interested in questions of how neural structures work together to create systems able to accomplish behavioral tasks.

Our primary current projects are in the interaction between multiple learning systems (such as hippocampus, cortex, and striatum) in the ability to make decisions, particularly deliberative decisions. We have ongoing neurophysiological projects examining the dynamics of neural ensembles
during decision-making processes, computational projects examining
the implications of these processes on addiction and other decision-making dysfunctions, and engineering projects developing new recording systems.
