The Hwang lab conducts research to understand the neural mechanisms of executive functions. Specifically, we are interested in discovering the neural architecture, processes, and dynamic systems that allow brain networks to select, inhibit, transfer, and integrate information. Together, these mechanisms support many important mental functions, 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, eye tracking and behavioral testing.
