He has done early pioneering works in developing real-time functional magnetic resonance imaging that are used to interpret the human mind, and applied the technology to interface the brain function with machines and computers. Later, he developed a new mode of non-invasive brain stimulation modality which utilizes the focused ultrasound waves to control regional neural functions, including the activity of the brain. He is primarily interested in advancing the technique for various neurotherapeutics, but also likes to seek out new ways to link thought/brain processes between individuals. Seung-Schik also developed a three-dimensional bioprinter that can ‘print out’ artificial brain tissues and organoids for potential applications in neural computers and medical applications.
