Michio Sanjo was awarded a doctor’s degree in 2003 from Kyoto University under Prof. Iehisa Nezu. He has been working on hydraulics as an associate professor at Kyoto University for years. He specializes in the experimental investigations of turbulence phenomena in open-channel flows, such as the secondary currents, horizontal vortex, free-surface divergence, gas transfer and influence of bottom roughness. Further, He conducted field works with development of the autonomous robot boat for automatic velocity measurement in river.
