Research Overview

I have expertise in neuroimage analysis using structural and diffusion magnetic resonance imaging (MRI) and I have been focused on development and analysis of quantitative neuroimaging features of normal and abnormal brain development. I have developed methodologies for quantifying and investigating early cortical structural development, and for examining white matter connectivity patterns based on individual’s cortical gyral patterns. My long-term goal is to provide a novel and unique imaging biomarker for genetic brain disorders, and develop my career as a pioneer in a translational research filed of the developmental neuroimaging. To that end, I have been studying various developmental brain disorders using my original MRI analysis techniques and showing the potential to really diagnose developmental problems in multiple disorders (polymicrogyria, developmental dyslexia, tuberous sclerosis complex, and TUBB3 syndromes).
