Jinwon Chang is an undergraduate student at Williams College and a research assistant with a strong interest in sleep EEG dynamics, particularly in relation to psychiatric disorders and brain stimulation. His research focuses on applying quantitative EEG methods to investigate neural oscillations, sleep-related brain activity, and their potential clinical relevance. He is especially interested in how electrophysiological markers can help clarify mechanisms underlying neuropsychiatric conditions and treatment effects.
