Dr. Taka-hisa ARIMA is now leading a group in RIKEN Center for Emergent Matter Science, Japan. He is also a professor at Department of Advanced Materials Science, the University of Tokyo, Japan. His research field is exploration of functional condensed matters which exhibit various interesting emergent phenomena such as superconductivity, colossal magneto-resistance, and giant magneto-electric effects, with the help of synchrotron x-rays, neutrons, and high-energy electron beams.
