Research Interests:

Dr. Hazlett coordinates and supervises two longitudinal neuroimaging projects investigating brain development in neurodevelopmental disorders.  Currently, the projects involve performing brain scans using MRI on young children (1½ to 5½ years old) with autism, developmental delay, fragile x disorder, and typical development. MRI scans and psychological assessments are used to track the maturity of the children across two time points. By comparing the brain development of the typically developing children to those that have a neurodevelopmental disorder, our research team hopes to learn more about the brain structures involved in these disorders. The researchers use sophisticated brain imaging software that allows them to measure the size and shape of brain structures.
