General Engineer at DCMA reviewing F-35 and F-22 material risks and manufacturing processes.

United States

Message

At the Defense Contract Management Agency, I led the F-35 and F-22 Material Review Board group, evaluating variance requests for engineering adequacy, safety, cost, and function. I also led evaluations of the F-35 configuration management process and reviewed technical data packages with CATIA.

Earlier, I worked on aircraft testing and structural analysis at USAir Force EdwardsAFB, and on automotive engineering at BKT Group, Chrysler LLC, Edscha NorthAmerica, and DOW Chemical. My work included vehicle NVH and crash analysis, finite element modeling, test plans, and patented composite and acoustic components.
