Research Interests

Dr. Hideki Koizumi got involved in research and development of measuring technologies of trace elements (1974), magnetic resonance imaging (MRI, 1983), magnetic resonance angiography (MRA, 1985) and other major areas. Later, he expanded his areas with functional MRI (fMRI, 1992) toward brain-science and education; then science and ethics. His ideas were originated from basics of manufacturing with deep and wide thoughts. He invented the polarized Zeeman atomic absorption spectrometry, which has enabled us to measure more minor elements. In 2013, this was certified as Heritage Analytical Techniques and Instruments, and Scientific Instruments by Japan Analytical Instruments Manufacturers' Association (JAIMA). His scientific interests, through development of medical devices, have been grown to brain sciences and more thinking in abstractions. Since 1995, his Optical Topography System has attracted world-wide attention and appreciation. In January, 2003, this was chosen as one of the four major techniques which have broken the mold in MIT Technology Review magazine which was established in 1899.
Hitachi, Ltd. has chose Dr Koizumi as the Fellow because of his finest performance which was globally recognized. He is the fifth Fellow of Hitachi.
He is now working as Executive Vice President and Chair of the Committee on International Affirs of Engineering Academy of Japan (EAJ). His knowledge and experiences has greatly contributed to engineering international networking as well as research and education.
