Professor Seed's published nearly 300 papers and reports on various topics on Geotechnical Engineering. His early research on pile-soil interaction, soil compaction and pavement formed the scientific basis for modern design. In the 1960s he established a new research area, geotechnical earthquake engineering, and he is commonly regarded as the founding father of this area. His pioneering works included the development of equivalent linear method (SHAKE) for seismic site response analysis, soil structure interaction analysis, evaluation and mitigation of soil liquefaction, etc. He investigated many major disasters, such as the 1964 Great Alaska earthquake, the 1971 San Fernando earthquake in California, the 1976 failure of the Teton dam, the 1979 slide at the port of Nice in France, and the 1985 Mexico City earthquake. He served as a consultant on hundreds of projects all over the world, including more than 100 major dams, more than 20 nuclear power plants, and innumerable major buildings and transportation facilities. His research, founded on sound scientific principles, have led to a total revision of concepts and methods for geotechnical earthquake design, as well as revision of codes of practice, design procedures, and regulations throughout the world.
