His previous and ongoing research centers around the use of virtual reality as a tool to understand psychopathology (e.g., autism, schizophrenia, obsessive compulsive disorder, and personality disorder), the human computer interaction (HCI), and the treatment of children with autism spectrum disorder. During his engineering training and previous work at Hanyang University and Duke University, he did several interdisciplinary works which are related partially to psychiatry/psychology and partially to engineering. He also has several experiences with neuro-behavior, emotion, cognition, and cultural researches. He hopes that his research may contribute to solving social-science/medicine or engineering questions.
