Symposium in Honor of I. M. Idriss – June 17, 2016

The contributions of I. M. (Ed) Idriss to geotechnical earthquake engineering will be honored at this one-day symposium on the UC Davis campus. The program will include lectures by nine of his life-long friends and colleagues: J. M. Duncan, J. K. Mitchell, T. D. O’Rourke, K. H. Stokoe, R. Dobry, J. D. Bray, L. H. Mejia, N. Abrahamson, and R. W. Boulanger.

Proceeds of the symposium will go to the Mariam and Izzat M. Idriss Endowment Fund for Geotechnical Engineering Education. This endowment supports educational activities that enrich graduate school experiences in geotechnical engineering. We are especially grateful for the generous support provided by the geotechnical engineering community through their sponsorships.
