Since 2003, has been engaged in damage detection research, which was mainly carrying out bridge damage detection based on structural vibration and pipeline defect detection based on ultrasonic guided wave. Developed bridge damage detection method based on wavelet theory, and proposed weak guided wave signal detection method based on chaos sensitivity. In recent years, the research interests focus on the theoretical and experimental methods of micro defect detection in structures and materials, the history of mechanics and methodology. Has experience in the area of Nonlinear Dynamics, Small Defect Detection, Signal Processing, Measurements technique, etc.
