He is a recipient of the Shamsher Prakash Award and the NSF Presidential Young Investigator Award. Elgamal was also a Lilly Teaching Fellow (1991-1992). He is a member of the American Society of Civil Engineers. Professor Elgamal served as chair of the Department of Structural Engineering from 2003 to 2007.

Professor Elgamal is an expert in earthquake engineering and computational geomechanics. Incorporation of emerging information technologies into structural engineering is currently one of his main research areas. Internet applications include sensor networks for monitoring our civil infrastructure, with real-time condition assessment and decision-making algorithms. Integration of research and education with live web-accessible experiments is a main component.

Yewei Zheng, M.S., Ph.D

Yewei Zheng is currently a Post Doc in the Department of Structural Engineering at University of California, San Diego (UCSD). He received his M.Sc. in Geotechnical Engineering from University of Oklahoma (OU) and B.E. in Civil Engineering from Huazhong University of Science and Technology (HUST) in Wuhan, China. He is now working on numerical simulations and reduced-scale shake table tests of geosynthetic-reinforced soil bridge abutments under the supervision of Professor Patrick J. Fox and Professor John S. McCartney. In this study, reduced-scale shake table tests will be conducted to characterize the seismic performance of GRS bridge abutments. Numerical simulations will be performed to investigate the behavior of full-scale GRS bridge abutments under seismic loading. Results of this study will be used for developing seismic design guidelines for GRS bridge abutments.

Robert Caulk, M.S. (Webmaster)

Robert is currently a PhD student at UCSD working to improve the viability of sedimentary based Enhanced Geothermal Systems. His research is focused on computationally investigating fracture mechanisms associated with hydraulic fracture propagation. In addition to open source discrete element code development, he has experimentally investigated fracture aperture/permeability change in EGS, he has optimized energy pile heat exchanger layouts, and he has demonstrated the viability of reusing abandoned oil and gas wells for geothermal purposes.

John Li, M.S. (Treasurer)

John Li is pursuing a PhD degree under supervision of Professor Ahmed Elgamal. He was born in the United States, and have lived in Los Angeles, California before the college. He held both BS and MS degrees at UCSD structural engineering. He has been working with Professor Elgamal since he was a senior student. His current research focuses on soil-structure-interaction for large embedded structures, more specifically a two scaled models of a nuclear power plant in close proximity. In the scope of this research, he made use of the available data to extract the soil properties, which were shown to provide a reasonable match to the recorded data. Using the extracted properties, a parametric computational study was conducted to illustrate the salient mechanisms associated with the seismic response of such large embedded structural systems.

From the earthquake engineering point of view, Highway Bridges are among the critical lifelines that receive much attention. Smooth operation of the Highway system after a major earthquake, facilitates the critical rescue and recovery efforts. Disruption of function can also result in substantial wide-scale economic consequences. In this context, the seismic response of bridge seismic response is being investigated from a system level perspective. The deck, columns, abutments, and foundation response mechanisms are integrated within a unified framework. Systematic evaluation of the global system response is conducted under a wide range of expected earthquake input shaking scenarios. For that purpose, calibrated computational models and representative site specific recorded ground motions are employed. Results of this study are presented, for a number of large bridges with different structural response characteristics, in terms of the bridge geometric configuration, spatial extent, and the underlying ground/foundation properties. Insights are drawn, along with recommendations for routine application of the developed state-of-the art analysis techniques.
