| Nagaraja Iyyer, Ph.D., Director of Engineering - Falls Church |
Dr. Iyyer has over 25 years of experience in aircraft structures engineering and application program development. The majority of his experience has been supporting the US Navy in its aircraft structural life surveillance and service life assessment and extension programs of various aircraft. His strengths are in solving fleet problems related to structural integrity issues and has been heavily involved in the development of aircraft mission profiles, ground and flight loads tests, aircraft usage surveys, and numerous fatigue tests including full-scale, component and coupon tests. Dr. Iyyer has conducted numerous risk assessment studies to support safety of flight decisions for various aircraft components. In addition to structural integrity issues, he has also worked in developing algorithms for distributed interactive fire mission systems for the US Army. His current interests are in developing reliable life prediction models for engineers and management, identifying and mitigating age-related problems, and developing new damage detection techniques. Dr. Iyyer has won numerous awards during his career, including the 2006 Naval Air Warfare Center Division's Area Commander's Award for his ground breaking development of a probabilistic risk assessment methodology and metrics to quantify the risk of continued US Navy P-3 flight operations. Dr. Iyyer is very proficient at computer programming and fluent in multiple computer systems and software applications.
