Research Interest Summary

Neural basis of action planning, decision-making and skill learning.

Broadly, my research program examines how the connective architecture of sensorimotor circuits (e.g., how neural circuits are wired together and the integrity of these connections) constrains cognitive function. As such I set out to capture general principles that explain: 1) how the configuration of corticostriatal circuits provide clues as to their functional dynamics and behavioral decisions; 2) how differences in the organization of sensorimotor pathways predict differences in decision-making and learning; and 3) how context (e.g., physical health, environmental factors and individual experiences) impact the physical architecture of corticostriatal circuits and how this, in turn, impacts cognition.
