Summary

Over the past ten years my research and practice in Geo Engineering have primarily focused on (i) characterization of soil properties by in situ and laboratory tests; (ii) onshore, nearshore, and offshore foundation response; and (iii) geotechnical earthquake engineering. These studies have focused on mechanisms influencing soil behavior, with validation through specific case histories and predictive performance relative to large global databases. Frameworks based on analytical solutions and/or mecahnically based empirical relationships are necessary for these studies, particularly when extrapolating to conditions outside the specific database used to validate a proposed solution. Current research is continuing in those areas, primarily focusing on foundations for offshore wind turbines, quantification of resistance factors for Load and Resistance Factor Design (LRFD) of deep and shallow foundations, as well as developing reliable methods to evaluate deformations of transportation structures and serviceability limit states. Organization of experience is primarily based on soil behavior evaluated using seismic piezocone tests.
