He and has been working in the area of 3D printing for more than 30 years, on VR simulation for more than 25 years and in micro/nano technologies for the past 20 years. The main focus of his work has been 3D modeling, design and VR simulation in manufacturing and assembly, medical application, large-scale dynamic simulations in various research organizations in Japan such as Hokkaido University, Tokyo Metropolitan Institute of Technology and 3D Incorporated and Virtual Reality Center Yokohama (CTO), UCLA (2001-3) and NIST (2002-3). At NIST he was responsible for industrial Virtual Reality Assembly (VADE) and the optical nano-tweezers group. His work in hybrid metal and casting 3D printing for functional prototyping has been patented (pending) in recent years.
