Research Description:
My research examines how brain development is altered in individuals with developmental disabilities. I am using human pluripotent stem cells to study the formation of the cerebral cortex. The cerebral cortex is the most complex area of the brain and is responsible for functions unique to humans, such as language and abstract thought. Problems with any of the cerebral cortex’s crucial development steps can lead to intellectual disability.
My goal is to use stem cells to examine the alterations that occur in cortical development with a current focus on Down syndrome. These studies will not only shed light on brain development in developmental disorders but will help our understanding of human brain development in general.
