D. course, he worked for the Power-reactor and Nuclear-fuel Development Corporation, PNC (now Japan Atomic Energy Agency, JAEA) in Tokaimura, Japan, as an engineer, a researcher, and a vice-chief-researcher, all permanent position, in 1996, 1997, and 1998 respectively.  From Aug. 1998 to Mar. 2000, he worked for Hokkaido Univ. in Sapporo, Japan, as a postdoctoral fellow of Core Research for Evolutional Science and Technology (CREST) sponsored by Japan Science and Technology Corporation (JST) in Kawaguchi, Japan.  From Apr. 2000 to May. 2002, he was a Research Associate of the Department of Media and Telecommunications Engineering, Ibaraki Univ. in Hitachi, Japan.  From Jun. 2002 to Mar. 2009, he was an Assistant Professor of the same department, Ibaraki Univ. in Hitachi, Japan.  From Apr. 2009 to Mar. 2018, he was an Associate Professor of the same department, Ibaraki Univ. in Hitachi, Japan.  From Apr. 2010 to Mar. 2023, he was also been an Associate Professor of Frontier Research Center for Applied Atomic Science(iFRC), Ibaraki University in Tokaimura, Japan.  Since Apr. 2018, he has been an Associate Professor of the Department of Electrical and Electronic Systems Engineering, Ibaraki Univ. in Hitachi, Japan. He runs the laser engineering laboratory of the department.  From Feb. 2003 to Mar. 2003, he was a Visiting Professor of the Department of Physics, Univ. of Toronto, Canada.  Since Apr. 2004, he has been a Visiting Scientist of RIKEN in Wako, Japan. 

    His research interests include

    He is a member of the Japan Society of Applied Physics (JSAP) and the Institute of Electrical Engineers of Japan(IEEJ), a senior member of the IEEE (Photonics Society), a senior member of the Optica, formerly the Optical Society of America (OSA), a senior member of the Institute of Electronics, Information and Communication Engineers (IEICE), and a senior member of the Laser Society of Japan (LSJ).     2002/05/01-2003/05/31 Editorial board member of LSJ, 2010/05/17-2011/03/31 and 2020/04/01-2021/03/31 Conference program committee of LSJ, 2009/05/01-present Ultrafast Opto-electronics (UFO) committee on electronics society of IEICE, and 2019/06/01-present coherent light source technology commitee of IEEJ.

    Brief description of what he has done is "Chirped pulse amplification (CPA) with original regenerative amplifier, First Transparent material processing with femtosecond Ti:S CPA laser system. Programmable optical pulse compression to 7 fs using a spatial light modulator within pulse shaper"and "Finite difference time domain (FDTD) calculation for an ultrashort light pulse propagation in an optical fiber."   To summarize, he experimentally demonstrated a programmable chirp compensation using a spatial light modulator (SLM) in a pulse shaper resulting in a 7.1-fs transform-limited pulse compression for continuum pulses broadened from 670 to 950 nm in a silica fiber and compared with the FDTD calculation results.
