Research Statement

My research is focused on the use of advanced Magnetic Resonance Imaging (MRI) for mapping and measuring brain structure, tissue microstructure and functional organization. These techniques are being used to investigate the brain in both typically developing individuals and subjects across the lifespan. My lab is developing and applying leading edge imaging technologies to investigate novel brain measures.  This includes the development of innovative rapid, high resolution, high sensitivity and quiet diffusion-weighted imaging techniques and relaxometry mapping with motion correction. We will be leveraging the unique capabilities of the new MAGNUS MRI brain imaging system at the Waisman Center.  We are also developing novel image analysis strategies for characterizing individual differences and heterogeneity to better appreciate neurodiversity across specific populations. These technologies are being applied to research studies in a broad range of populations including early brain development and aging with specific studies focused on autism, cerebral palsy, Down syndrome, traumatic brain injury, and dementia.
