Yuichi Murai received his Ph.D. in Mechanical Engineering in 1996 at The University of Tokyo, Japan. He worked at Fukui University as a research associate from 1995 to 2000 in nuclear engineering, and at London Imperial College from 2001 to 2002 for laser measurement of combustion flows. He moved to Hokkaido University in 2003 as an associate professor and became a professor in 2010 at Laboratory of Flow Control (LFC), Hokkaido University. He published 160 journal articles and 350 international conference proceedings papers in the field of experimental fluid mechanics such as for Particle Image Velocimetry and Ultrasound Doppler Velocimetry, mainly targeting multiphase flows. His latest focuses are industrial applications of his measurement instrumentations for drag reduction ships, advanced wind turbines, and pipeline systems upon global demands for current energy issues. He is in charge of associate editor of Experiments in Fluids (Springer) and governing board chair of International Conference of Multiphase Flow (ICMF).
