Research Interests

Professor Ansari’s technical areas of interest include the broad discipline of Structural Engineering with emphasis in Structural Health Monitoring (SHM); smart sensors; and Nondestructive Testing (NDT).

Current research topics include: Integrated Fiber Optic Sensors for Condition Monitoring of bridges; Fiber Optic Acoustic Emission Sensors for real time monitoring of corrosion and fracture; Development of MEMS based sensors for civil structural systems; Optical Fiber Distributed Sensor for Post Seismic Monitoring of Damaged Structures; Monitoring the state of repaired and Strengthened structures; Development of weigh-in-motion (WIM) systems; Image Processing Techniques for Characterization of Entrained Air Bubble System in Concrete.

Research Laboratory

Our specialty is in structural health monitoring. We build fiber optic sensors and then install them in bridges, dams, buildings, and tunnels. Our capabilities are unique since we are structural engineers with expertise in fiber optic sensors. We build the sensors as well as the interrogation units. These sensors are tested in our structural testing facility for validation and mock up experiments prior to field installations in bridges and other types of structures. Because of our special capabilities our sensors withstand the harsh construction environment and yet capable of measuring the specific parameters they were designed to monitor.

We also perform nondestructive tests (NDT) using acoustical as well as optical methods including ultrasonics, acoustic emissions, stress wave techniques, resonant frequency, and laser holography. NDT in our laboratory is primarily used for investigation into the quality and condition of concrete pavements and bridge decks during the construction and or their service lives.

As an academic entity, the most important product of our laboratory is our students. My students will all develop the unique expertise in sensors, NDT, and structural health monitoring by the time of their graduation.
