He received his bachelor’s and master’s degrees in civil engineering from Nihon University in 1982 and 1984, respectively, and his PhD from Nihon University in 1995. He worked at Kumagai Gumi Co., Ltd. from 1988 to 1996. While working at the Technical Research Institute, his major research topics were experiments to verify the effects of a new wave-dissipating block. After retiring in 1996, he moved to the Civil Engineering Research Laboratory where his major research topics were erosion control by torrent and river model experiments. In 2008, he moved to Nihon University to expand his research topics to sedimentation in rivers, landslide dam failure with wood debris, and debris flow in volcanic areas. Dr. Oda is a member of the Japan Society of Civil Engineering (JSCE) and the Japan Society of Erosion Control Engineering (JSECE).－　　－12Research AchievementsAkira ODAProfessor, Department of Civil Engineering
