Research Interest

My research spans the fields of dynamics, vibration, control, applied mechanics, structural health monitoring, and wind energy, and integrates analytical development, numerical simulation, experimental validation, and industrial application. Much of the current research can be divided into three areas: 1) vibration and stability of distributed structural systems; 2) finite element modeling, modal testing, model updating, and structural damage detection; and 3) infinitely variable transmission and wind energy. In the first area, we have developed new methodologies for analyzing and controlling the vibration of linear and nonlinear, time-invariant and time-varying, distributed-parameter systems. In the second area, we have addressed some major challenges in model-based damage detection: accurate modeling of structures and inverse analysis for damage detection. In the third area, we are developing novel all-geared infinitely variable transmission and variable electromotive-force generators.

My laboratories, the Dynamic Systems and Vibrations Laboratory in Room 236 of the Engineering Building and the Laser Vibrometry Laboratory in Room 233I of the Engineering building, have a state-of-the-art vibration measurement and analysis facility, and various specialized test stands have been developed in-house for experimental validation purposes. Our research has been supported by the federal and state government as well as industry. In addition to training graduate and undergraduate students, the laboratory has provided outreach programs to K-12 students in the Baltimore region.
