Other Activities within Engineering and Teaching Professions

·          Presented five short courses in Nevada and California on Liquefaction, Seismic Bridge Abutment Design, and Seism ic Response; Delivered as many as 70 presentations in conferences, meetings, and seminars.

·          Received 1997 Shamsher Prakash Foundation Citation for the work on Dynamic Soil-Structure Interaction and Stability of Retaining Structures under Earthquakes.

·          Investigator (PI and Co. PI) of projects totaling more than $2.4 million from a wide variety of sources including, federal (NSF, ARO, DOE, NCHRP, Engineering Foundation), state (Nevada, California), and other sources (e.g. SCEC, EPRI, MCEER).

·          Developed many software- notable ones are TARA and MOVLOAD. A modified version of TARA program is routinely used by WES in their seismic response analyses of dams. 

·          Served as a Member of many ASCE Technical Committees (Soil Dynamics, Computer Applications, Shock and Vibratory Effects) and EERI and had been a reviewer of proposals and reports for the NSF, ASCE, and US Army.

·          Awards:

1996 EERI Student Research Paper Competition Award was presented to Mahmoud EL- Gamal.  His paper was based on his Ph.D. work carried out under my supervision.

1997 Shamsher Prakash Foundation Citation for work on Dynamic Soil Structure Interaction and Stability of Retaining Structures Under Earthquakes
