Contributions (Publications/Research Activities)
Soon after receiving his Ph.D. from the University of British Columbia, Canada, he joined University of Nevada, Reno in 1984. He developed a two-dimensional effective stress based computational model (TARA) to study seismic response evaluation of soil structures. A revised version of this computational model is being widely used by the Waterways Experiment Station (WES) in their seismic evaluation of many dams located around the country. He has authored over 150 publications in journals, national and international conferences and technical reports. The research contributions have been in many diversified disciplines, including, geotechnical-earthquake engineering, offshore engineering, and transportation engineering. He was directly responsible for research projects totaling more than $3.0 million and as a co-investigator capacity in projects totaling more than $4.7 million. Sponsoring agencies include, Engineering Foundation, National Science Foundation (NSF), Electrical Power Research Institute (EPRI), NOVOPHALT Inc., Nevada Department of Transportation, California Strong Motion Instrumentation Program, Department of Energy (DOE), Nevada Nuclear Waste Project Office (NWPO), US Army Research Office, and Southern California Earthquake Center. He has been involved in two independent seismic soil response verification studies: NSF-VELACS study and EPRI study. In the VELACS study, his code was used in a “verification” exercise using extensive laboratory-centrifuge test results.
He has been devoted to continuing research in many areas of soil dynamics. His contribution spans a variety of topics including, (1) seismic behavior of soils and structures (liquefaction, site-specific soil response, permanent deformation behavior of flexible and rigid retaining wall and bridge abutment and piles), (2) wave-soil interaction, (3) pavement material characterization and pavement response analysis, and (4) earthquake risk and nuclear transportation risk studies. His extensive list of publications, professional, service, and research grant activities exemplify his contribution.
In recognition of his contribution, he was awarded the 1997 Shamsher Prakash Foundation Citation for work on Dynamic Soil Structure Interaction and Stability of Retaining Structures under Earthquakes.
Involved in a variety of consulting projects for a number firms including, Klohn Leonoff Consultants, Vancouver; Komex Consultants, Calgary; Exxon, Houston; GAB Corporation, Sacramento; Welsh Engineers, Denver; Pezonella Associates, Reno; EIC Consultants, Denver; Golder Associates, Denver; Harding and Lawson Associates, Reno; WESTECH, Reno; SEA Engineers, Pacific Engineering and Analysis, California; Summit Engineers, Reno; Lumos Associates, Reno; CNI Inc., Tucson; Bently Holdings, California; Maritime International, Louisiana.; SaLUT, Inc., Maryland; Lawrence Livermore National Laboratory, CA; Freeman, D’Aiuto. Pierce, Gurev, Keeling, and Wolf, Stockton, CA, Weidlinger Associates, NY; Wood Rodgers, NV; Corrollo Engineers, CA.
The above projects involved many geotechnical seismic design issues that included site-specific response analyses, soil-structure interaction, liquefaction and permanent deformation.
