  I am currently a Ph.D. candidate in Haptics and Virtual Reality (HVR) Laboratory at Pohang University of Science and Technology (POSTECH) under the supervision of Prof. Seungmoon Choi. Specifically, I am focusing on the development and evaluation of the expert driving skill modeling and training (education) to novice drivers in virtual environments using artificial neural networks and haptic assistance. I have a strong interest in the implementation and validation of haptic technologies and applications, for various relevant research areas including human skill modeling / learning / transfer, human computer interaction / human robot interaction, perception / psychophysics, cognitive science, and virtual reality. I have participated in other research topics: such as mid-air laser haptics, haptic memorization methods, English education using haptic feedback, haptic refrigerator prototyping, etc.
