Research Interest Summary

Cognitive and educational neuroscience of reading, language, math, and learning.

Research Interests

My lab relies upon a broad-based and interdisciplinary cognitive neuroscience approach to address questions that fall within two predominant strands of research. One strand is focused on the neural basis of language processing. Topics of interest include the articulatory and phonological codes involved in verbal working memory, and the ways in which different writing systems influence the representation and processing of orthographic information. A second strand is focused on basic learning systems in the human brain. We are especially interested in how cognition may be optimized by reinforcement learning signals mediated by the basal ganglia and error-correction signals mediated by the cerebellum.
