Advances in neuroscience have allowed researchers to explore the functional and structural organization of the human brain in ways never before possible. Some brain areas are broadly engaged across a multitude of human experiences, while others are only involved in very specific cognitive tasks. But how do particular brain areas become responsible for particular cognitive functions? How does this functional organization arise in development, and how does it change with traumatic injury and pathology? My research aims to answer these questions and to uncover the physical mechanisms underlying the functional differentiation of the human cortex during development, adulthood, and its plasticity in response to disorders and injury of the brain. I have shown that neuroanatomical scans alone can predict brain function and outcome, e.g. scans in children, even before they can read, can predict later reading development and dyslexia and scans in adults with social anxiety disorder can predict whether a specific treatment is likely to succeed for each individual. My work aims to offer powerful new strategies to understand, diagnose, and predict treatment outcome in both clinical and neurodevelopmental disorders, as well as plasticity and response to disease and trauma (e.g. traumatic brain injury and concussions). I use a variety of methods in developmental, computational, and cognitive neuroscience, including behavioral measures, fMRI, diffusion-weighted imaging (DWI), functional connectivity, modeling, and developmental neuroimaging. I obtained an Sc.B. in Neuroscience from Brown University, working with David Sheinberg and received my Ph.D. in Systems Neuroscience from MIT under the mentorship of John Gabrieli and Rebecca Saxe. I completed my postdoctoral fellow with Nancy Kanwisher at MIT in collaboration with Bruce Fischl at MGH.
