Dr. Hui Chen, developer of the PreVABS program, received his PhD in Mechanical Engineering from Duke University in 2004. He has served as Senior Structural Analyst at GulfStream Aerospace Corporation, performing stress analysis of fuselage airframe structures. Prior to this he was an Aeronautic Engineer at Groen Brothers Aviation, where he was responsible for rotor blade and rotor system structural analysis and flight simulation. Before joining Groen Brothers Aviation, Dr. Chen was a Senior Engineer for Structural Dynamics Analysis at the China Helicopter Research and Development Institute, conducting stress and dynamic analysis of airframe structures. He has also served as a Research Assistant at Utah State University, where he authored the PreVABS program, an advanced high-fidelity and computationally efficient tool for realistic design and analysis of sophisticated composite rotor blades and wing structures. Dr. Chen has extensive knowledge in solid mechanics, computational mechanics, linear/nonlinear FEA, mechanics of composites, nonlinear dynamics, and fatigue theory, as well as industry experience in analysis of metal and composite structures, scientific computing, programming, and experimental techniques. He additionally has over 20 academic publications and is a member of the American Society of Mechanical Engineers (ASME), as well as the American Institute of Aeronautics and Astronautics (AIAA). Dr. Chen has been twice awarded the Advanced Science and Technology Award of Aviation Industries of China (AVIC).
