Dr. David Chelidze received his Ph.D. in Engineering Science and Mechanics from Penn State University in 2000. His main research expertise is in analytical and experimental nonlinear dynamics and data-based health monitoring of engineered and natural systems. His current research (sponsored by NSF, NIH, US Army, ONR, and AFRL) focuses on nonlinear dynamics and vibrations of structures, reduced-order modeling, structural damage identification and prediction, and identifying and predicting fatigue. He is a recipient of the NSF CAREER award, and Edmund and Dorothy Marshall Award for Faculty Excellence in Research.
Research
Analytical and experimental nonlinear vibrations and dynamics; vibration-based structural health monitoring; dynamical systems perspective on fatigue evolution; modal testing and analysis; dynamics, control and stability of engineered systems. The main research goal is to synthesize knowledge from fields such as dynamical and stochastic systems, linear and nonlinear time series analysis, multivariate analysis, and estimation and filtering theory to develop and implement innovative techniques for modeling, simulation, control, diagnosis, and prognosis of engineered and biological systems.
