Dr. of Engineering
Field of Specialization
Biomedical Engineering, Neuroimaging, Neuroinformatics
Outline Activities
There are two major research fields. One is the functional brain imaging which aims at the elucidation of human brain function; the other one is brain function modeling which is applied to various fields by constructing the model of brain activation. In details, we study in the fields of the measurements of brain function by EEG (Electroencephalography), MEG (Magnetoencephalography), MRI (Magnetic Resonance Imaging), NIRS (Near-Infrared Spectroscope) and TMS (Transcranial Magnetic Stimulation), the development of measurement technology and the simulation of brain activation. The elucidation of the mechanism of brain function is one of foundations of life science, and it can be applied to almost all the fields. Have a deep understanding of brain information processing, and apply the research results to fields of life science, medicine, engineering and education is the purpose of our study.
Since we are studying in an interdisciplinary domain, we take into account the collaboration of medicine, biology, pedagogy and psychology is important in our study.
