The Hwang Lab conducts research to discover the neural, cognitive, and developmental dynamics of cognitive control. Specifically, we are interested in the neural architecture and dynamic processes that allow brain networks to select, inhibit, transfer, and integrate information for goal-directed behaviors. Together, these mechanisms support many important mental functions during typical and atypical development, such as attention, working memory, response selection and inhibition. We address our research questions with a comprehensive human neuroscience approach, combining multimodal research methodologies, including fMRI, EEG, TMS, lesion studies, eye tracking and behavioral testing.
