Jonathan D. Bray

Jonathan D. Bray (born before 1981) is an American civil engineer specializing in geotechnical engineering.

Bray studied at the US Military Academy in West Point with a bachelor's degree in 1980 and at Stanford University with a master's degree in structural engineering in 1981. He then worked for the US Army Corps of Engineers, including in Korea. He received his PhD in geotechnical engineering from the University of California, Berkeley , in 1990 . He started the dissertation under Harry Bolton Seed , who died in 1989 (afterwards his son RB Seed was the supervisor of the dissertation). He was then a lecturer there, was an assistant professor at Purdue University in 1990, assistant professor in 1993, associate professor in 1996 and, from 1999, professor at Berkeley.

He is particularly concerned with geotechnical aspects of earthquakes. At the Corps of Engineers he worked on the consequences of the Loma Prieta earthquake in 1989 and at Berkeley he studied the dynamic behavior of dams damaged by this quake. To this end, he developed finite element programs for the interaction of soil and structures (SSCOMPPC).

He gave the 25th Buchanan Lecture, the 6th Ishihara Lecture, received the Ralph Peck Award in 2013 and the Terzaghi Award in 2018 . He was a Presidential Young Investigator in the 1980s, was a Packard Fellow in the 1990s and received the 1997 Walter L. Huber Prize of the ASCE , of which he is a fellow. He is a member of the National Academy of Engineering (2015).
