Dexter Johnson Technical Fellow for Loads and Dynamics NASA
AIAA SciTech Forum 2022
Dr. Johnson began his NASA career in 1990 at the NASA Glenn Research Center (GRC), as an Aerospace Research Engineer where he was involved in the development and application of Magnetic Suspension Technology to Advanced Aerospace Turbomachinery. He is the inventor of the Adaptive Variable Bias Control method for power-saving operation of Active Magnetic Suspension Systems. Later he held positions as the acting Deputy Chief of the Life Prediction Branch and the acting Chief of the Controls and Dynamics Technology Branch. In 2006, he became the Chief of the Structural Systems Dynamics Branch, and he served as the Chief of the Structural Dynamics Branch at GRC from 2014 - 2018.
Before joining the NESC as the NASA Technical Fellow for Loads and Dynamics, Dr. Johnson served as an active member of the NESC Loads and Dynamics Technical Discipline Team, and served as the GRC Loads and Dynamics Capability Leadership Team Discipline Lead since the inception of the Agency's Technical Capability Assessment Team activities. He is an expert in Structural Dynamics and Controls focused on Launch Vehicle and Spacecraft Loads and Dynamics, Advanced Rotating Machinery and Electromechanical Devices for Aerospace Systems.
Dr. Johnson received his Bachelor of Science Degree in Aerospace Engineering and a Master of Science and Ph.D. in Mechanical Engineering from the State University of New York at Buffalo.
