Dr. Tomoya Okino is a researcher of attosecond science research team at RIKEN Center for Advanced Photonics, Japan. He received his Ph.D from the University of Tokyo in 2009. He has served as Assistant Professor at the Department of Chemistry, School of Science, the University of Tokyo from 2006 to 2012. He has been involved in the investigation of ultrafast hydrogen migration process in intense laser fields and the development of new attosecond nonlinear spectroscopic method for attosecond molecular dynamics. His current research interest is visualizing and controlling chemical reaction with attosecond temporal and sub-Angstrom spatial resolution.
