Dr. Kyongje Sung is an expert in Quantitative and Mathematical Psychology/Cognitive Neuroscience who joined ECAE in August 2020 after a decade of professional experience in several academic institutions across USA.
Dr. Sung received his graduate training at Purdue University, after which he joined the Center for Cognitive Neuroscience at Duke University in North Carolina as a postdoctoral associate. In 2008, he joined the Division of Cognitive Neurology/Neuropsychology in the Department of Neurology at Johns Hopkins University School of Medicine as a postdoctoral fellow. Later in 2010, he was promoted to a faculty position as a research associate.
Dr. Sung’s research topics include diverse levels of human information processing, from low-level visual perception to the higher cognitive functions, of healthy individuals and people with a mental condition, including schizophrenia, bipolar disorder, and autism. He adapted computational (simulation), electrophysiologic (EEG), and behavioral analysis (reaction times) techniques to answer the research questions.
His recent research focuses on the electrophysiologic investigation of early visual perception of individuals with autism, especially those with low-functioning autism. The main goal of Dr. Sung’s recent research effort is to identify the defining electrophysiologic characteristics in people with autism and to test non-invasive intervention methods, such as transcranial direct/alternating current stimulation (tDCS/tACS), as a potential intervention tool.
Dr. Sung received his Ph.D. from Purdue University in 2005 in Quantitative and Mathematical Psychology applied to human visual perception and attention. Before his time at Purdue, Dr. Sung received M.S in Cognitive Science from SungKyunKwan University, South Korea, and B.B.A in Industrial and Organizational Psychology from the same university.
