Professor David B. Bogy is the William S. Floyd, Jr. Distinguished Professor in Engineering. He was Chairman of the Department of Mechanical Engineering at UC Berkeley from 1991 - 1999, and he is the founding Director of the Computer Mechanics Laboratory. He is a member of the National Academy of Engineers, and he served on the U.S. National Committee on Theoretical and Applied Mechanics. He has served as Chair of the Executive Committees of the Applied Mechanics and the Tribology Divisions of the American Society of Mechanical Engineers. He received his B.S. Degrees in Geology and Mechanical Engineering in 1959, and his M.S. degree in Mechanical Engineering from Rice University in 1961. He received a Ph.D. degree in Applied Mathematics from Brown University in 1966 and spent a year as Postdoctoral Fellow in Applied Mechanics at the California Institute of Technology before joining the faculty of the Department of Mechanical Engineering at the University of California, Berkeley in 1967.

Professor Bogy's industrial experience includes work as a Mechanical Engineer for Shell Development Company where he conducted research in the mechanics of oil-well drilling. He also worked for two summers at the IBM San Jose Research Laboratory as a Faculty Fellow and consulted there for several years. He has also consulted for numerous other computer disk drive companies over the years. He has served as an expert witness in patent infringement suits in disk drive technology.

Professor Bogy's research interests are in solid and fluid mechanics as well as dynamics and tribology, especially as applied to computer technology, in particular data storage systems. He has also worked in static and dynamic stress analysis in layered elastic media. At UC Berkeley Professor Bogy teaches courses in dynamics, elasticity, elastic wave propagation and computer mechanics.
