Curriculum Vitae
Publication List

Biomedical engineering and vision is the main focus of Dr. Yagi's research. He has conducted research on a visual prosthesis, which is an artificial organ to restore the sight of blind patients with electrical stimulation to the visual nervous system. A second focus is human interface using biological signals such as EOG (electrooculogram) or EEG (electroencephalogram) for communicating better between a human and a computer. A third focus is a bio-mimetic robot vision system. A more complete list of publications can be obtained in his curriculum vitae.

Dr. Yagi received a Ph.D. degree in Electro-Mechanical Engineering from Nagoya University, Japan, in 1996 and became a postdoctoral fellow at the Institute of Physical and Chemical Research (RIKEN), Japan. He worked at Nagoya University from 1998 to 2001 as an assistant professor. During this appointment, he commercialized eye-gaze interface with SeaStar Corporation, and it appeared on the market in 2002. Just before that time, he was invited by NIDEK Co., Ltd. in 2001 to start directing the national research project of a visual prosthesis under the support of Japanese governmental agency, NEDO (New Energy and Industrial Technology Development Organization), and completed the first prototype of the visual prosthesis in 2004. After this, he moved to the Institute of Physical and Chemical Research (RIKEN) as a research scientist. He also held a research position as visiting research scientist at the University of Tokyo, Research Center fo Advanced Science and Technology, from Apr. 2004 to Mar.2005. Since September 2005, he joined the faculty at Tokyo Institute of Technology, Japan. He also had an appointment as a visiting research scientist at RIKEN till 2014. In 2012 and 2013, he was granted Fulbright visiting scholarship and held the position of visiting scholar at the Massachusetts Institute of Technology (MIT), USA. Currently, he is an associate professor at Tokyo Institute of Technology, Japan.
