Harry Yeh joined the faculty of Oregon State University in 2003, and is a Professor of Civil and Construction Engineering. His expertise is in the field of hydrodynamics associated with natural hazards, especially those in a wide variety of tsunami-related problems. His extensive experience of field studies includes the 1992 Nicaragua tsunami, the 1992 Flores tsunami, the 1993 Okushiri tsunami, the 1994 Shikotan tsunami, the 1996 Peru tsunami, the 1998 Papua New Guinea tsunami, the 2004 Great Indian Ocean tsunami, and the most recent 2011 Tohoku tsunami in Japan. He organized numerous multidisciplinary workshops including those on long-wave hydrodynamics and modeling, tsunami measurements, bathymetry and topography, seafloor deformation, tsunami laboratory facilities, tsunami deposits, data repository, and tsunami scenario simulations. The majority of his recent research activities are cooperative with applied mathematicians, numerical experts, mitigation strategists, and information technologists. He has extensive collaborative experience with Japanese scientists and engineers: for example, research program of structural control performance with Shimiz Corporation, laboratory experiments with Public Works Research Institute and University of Tokyo, collaborative engineering education with Tohoku University, and mitigation measures with Kyoto University.
