Leading geostructural and construction engineering practice including site characterization; foundation, earth retention and construction dewatering design; ground improvement (static & seismic) design for geohazard characterization and mitigation; geotechnical instrumentation and monitoring; numerical analysis.

1. Leading geotechnical design (foundation, excavation, ground improvement, etc.) for commercial, industrial, and federal projects, covering the Bay Area and Southern California, with total annual sales > $100 million.2. Coordinate developers, project managers and contractors throughout the course of design and construction. Serve as engineer of record during the entire project life cycle. 3. Develop and establish design specification, qualify control and quality assurance documentations. Conduct on-site quality and safety inspection during construction phase.4. Mentoring and training junior geotechnical engineers.

1. Co-lead geotechnical design for 4 offices, covering the Midwest and Northeast markets of U.S. with total annual sales > $100 million. Work with cross-functional teams to provide innovative and cost-effective ground improvement and support of excavation designs. 2. Manage and coordinate subsurface exploration, implement geotechnical instrumentation and monitoring programs for on-going projects in collaboration with owners’ geotechnical engineers. 3. Execute business development strategies based on market demand research and competition analysis for liquefaction-mitigation solutions in the Midwest (New Madrid Fault Zone).4. Increase market exposure by giving presentations for prospect clients at lunch & learn sessions, engineering workshops and industry conferences. Help prospect clients including engineering consultants, property owners and construction companies identify liquefaction risks in their up-coming projects, offer higher-quality and project-specific solutions.

Performance Evaluation of RAP Supported MSE Wall (funded by NE DOT)1. Conducted failure investigation on an MSE Wall supported by Rammed Aggregate Piers (RAP).2. Identified and numerically evaluated the contribution of deep-seated soft clay compression to the excessive settlement of the MSE Wall. 3. Identified the limitations of ground improvement technique such as aggregate/vibro piers in specific ground conditions.Mechanical Behavior of Gassy Silty Sand (funded by NSF)1. Designed and implemented laboratory program to characterize mechanical behavior of gassy silty sand.2. Experimentally validated the application of Terzaghi’s Effective Stress Principle to quasi-saturated soil with degree of saturation higher than 92%.3. Experimentally proved that increasing non-plastic fine content would dramatically counteract the increased cyclic strength gained by air-injection in loose liquefiable sand.4. Experimentally identified the susceptibility of gassy silty sand to collapse under subtle cyclic vibration.
