Seasoned self motivated professional with twenty years of Project and Program Management experience in the application of geosciences to the design of energy facilities. Conducted investigations for the specification of ground motion, seismic design parameters. Estimated seismic design ground motion for 10 nuclear power plants, and 4 high dams, and other critical energy facilities in the US and abroad on both deterministic and probabilistic basis. Conducted investigations to comply with applicable regulatory requirements, under an approved Quality Assurance Plan. Prepared many Safety Analysis Reports and defended results before Nuclear Regulatory Commission (NRC). Managed seismological investigations & geophysical surveys for the screening, selection and characterization of a site for High Level Nuclear Waste Repository Project. Conducted investigations to estimate volcanic and tsunami hazards to power plants and high dams. Conducted research in geosciences on my initiative and published more than 50 scientific papers in peer reviewed journals.
