Mr. Chang led the structural and lifing analysis for life-limited parts in the Global Material Solutions (GMS) program and was nominated for the American Society of Mechanical Engineers (ASME) Engineer of the Year award for his contributions to the GMS program. As a Patent Liaison, Mr. Chang evaluated and assessed the impact of patents on programs within aftermarket engineering and provided strategic guidance to the engineering staff.
