Teaching Assistant - Structural Dynamics, Structural Analysis, Material Mechanics

Research Assistant - TC Hsu Structural Research Laboratory.

Research assistant - Performed and coordinated multi-phase experimental research program funded by the National Science Foundation (NSF) and Texas Department of Transportation to determine the constitutive properties of prestressed steel fiber concrete Membrane elements. Membrane element behavior forms the basis of analysis for shear structures such as girder webs, reactor containment, and offshore platform structures. Maintained and upgraded facilities in the structural testing laboratory, including electrical systems, upgrade of panel element testing machine, and implementing safe work processes. Supervised and mentored four students for the NSF’s Research Experiences for Undergraduates (REU) program. Developed NSF research grant proposals in conjunction with prospective Principal Investigators.

Teaching assistant - Graduate and undergraduate engineering courses, taught lab classes, graded term papers, class assignments, design projects and tests. Organized tutorial sessions for students outside of class.

Engineering Manager

Performed structural design and electrical design commercial and light industrial projects, including foundations, multi-family, and wharves. Responsible for bidding & estimating, design, construction coordination and supervising staff of three engineers. Coordinate permitting requirements with Federal, State and Municipal authorities.

Regional Chief Construction Engineer (2002 - 2005)

Provide technical direction to construction engineers, superintendents, and site managers in constructability, staffing, scheduling, contracts and procurement for two national wireless telecommunications build-out projects.

Chief Rigging Engineer - Frederick, MD, Louisville, KY, Jamnagar, India (1994-2002)

Oversee a group of 12 engineers who develop and execute heavy lift rigging work on Bechtel jobsites. Provide technical direction and expertise for constructability, rigging planning, scheduling, and execution on jobs in power, refinery, telecommunications, and mining business lines. Develop rigging group staffing plan and assign staff to jobs as necessary. Coordinate and schedule Bechtel-owned heavy lift equipment, including hydraulic gantries, strand lift systems, transporters, and large cranes.

Senior Engineer

Responsible for all phases of light and heavy industrial rigging projects, including: design and analysis of special rigging components, construction procedures, reviewing bids, estimating costs, component fabrication, budget, and supervision of field construction personnel.

Structural Engineer

Performed structural design and analysis of structures and foundations for nuclear, coal-fired, and gas-fired power plants.

Structural Engineer

Designed structural systems for US Navy nuclear powered submarines (SSN’s and SSBN’s). Performed static and underwater shock analysis for the design of engine room and reactor compartment structural systems, including containment bulkhead substructures, tanks, main propulsion components, and pressure hull penetrations.
