We conduct behavioral and neuroimaging studies to examine how typical reading occurs in the brain and how brain structure and function change as children become more proficient readers.
Reading Disability: Dyslexia
We use behavioral and neuroimaging methods to better understand the origins of developmental dyslexia. We conduct research by comparing people with dyslexia to non-dyslexics to understand how brain structure and function differ. We also examine how intervention programs lead to structural and functional changes in children with dyslexia.

We study the neural basis of spelling, and how reading and spelling may have shared and distinct neural representations.

We using behavioral and neuroimaging methods to understand how mathematics and reading are related to one another, and in those with learning disabilities.

Math Disability: Dyscalculia
We are using intervention, behavioral, and brain imaging methods to better understand the origins of math learning disabilities (dyscalculia) and to understand why reading and math disability often co-occur together. We hope to gain a better understanding of the similarities and differences in children with deficits in reading and/or math.
Language Experience: Bilingualism
We are studying how learning (or knowing) two languages affects brain structure and function. We also study the effects of bilingualism on reading ability and other cognitive skills such as cognitive control.

We examine how sensorimotor systems develop and how they may be linked to reading and dyslexia.

Sensory Experience: Deafness
We conduct research that examines how sensory experience (e.g. deafness) is related to neuroplastic differences in the brain.
