Ph.D. Candidate in Civil Engineering - Structural Dynamics
Advisor: Professor Sami F. Masri
Thesis Title: Analytical and experimental studies in modeling and monitoring uncertain nonlinear systems

Research Experience

• Performed experimental and analytical studies in the system identification and structural health monitoring of nonlinear dynamic system, such as full-scale viscous dampers and magneto-rheological (MR) dampers. (Funded by Caltrans).
• Developed a real-time remote sensing system, installed on the Vincent Thomas Bridge ( Long Beach , CA , overall length 1844.04 m) for Caltrans. The bridge is equipped with full-scale viscous dampers for controlling wind-induced or seismic vibration. The developed remote sensing system continuously measures and records the dynamic response of the bridge under daily ambient excitation conditions, and special excitation conditions, such as earthquake.

• Performed experimental studies in the application of nuclear magnetic resonance (NMR) and magnetic resonance image (MRI) techniques to concrete materials. Studied extensively on the non-destructive evaluation (NDE) of chloride intrusion to cured concrete. Images of free chloride map were produced, using MRI techniques (one of the first chloride maps in concrete, using MRI technique).
• Studied the development of the MEMS-based NMR-on-chips, which are embedded into concrete to detect chloride attack to the reinforcement steel.
• Studied the applications of various sensing techniques for condition assessment of civil infrastructure, including classical and smart sensors, such as MEMS, RFID, and wireless sensors.

• Graduate course Computer Aided engineering Tools for Civil Engineering (12-740).
