Research Interests

Brain Development Imaging Lab - We study functional and anatomical brain development in neurotypical children and those with developmental disorders (especially autism). Research applies multimodal magnetic resonance imaging techniques (functional and functional connectivity MRI, anatomical volumetrics, diffusion tensor imaging and tractography, MR spectroscopy), as well as eye-tracking, behavioral, and neuropsychological measures.

Research Keywords: Brain development, autism spectrum disorders, functional MRI, diffusion tensor imaging, brain networks, cognition, emotion, sensorimotor function
