David began his career with GE Aircraft Engines in 1985 working on such projects a T700 production, GE36 design, CFE738 design, F412 design, and GE90 design, and CF34-8C design working on all rotating engine structures (high and low pressure compressors, high and low pressure turbines). David also conducted the life re-certification analysis for the CT7-5 LPT and similar work for the CT7-9 LPT.

In 2003 David’s company won a Phase I and later a Phase II SBIR with the US Air Force Research Lab/Materials Lab to develop a new methodology for determining the life consumed of highly-stressed rotating parts as a function of varied mission usage. More recently David teamed with Brayton Energy, LLC to develop a biomass and natural gas burning recuperated land-based power turbine in the 1.2MW class as well as structures design for a large scale solar energy farm in Arizona, and turbine design for an intercooled-recuperated turbo-shaft engine for an eighteen wheel application. He has also been a consultant to Samsung Techwin of Korea to assist in development of various frame and rotating components for the Korean Helicopter Program jointly developed with GE Aircraft Engines.
