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.

Our expertise is in structural health monitoring of civil infrastructure systems. We develop strategies for forensic analysis of bridges, buildings and other types of civil infrastructure facilities such as pipelines, and tunnels. Our capabilities are unique since we are structural engineers with expertise in fiber optic sensors. Depending on the application, we may either use discrete (FBG) or distributed sensors (BOTDA, Rayleigh, MZ, etc). The range of our structural health monitoring activities include design of the sensor system and wiring for the structure and problem to be solved; installation of the sensor system in the structure; installation of the interrogation unit and data acquisition system in the field; installation of the software specific for the parameters to be monitored; remote real time monitoring of the sensor data; analysis and recommendations. Examples of our projects can be found in our laboratory site (Please provide link to the laboratory site).As an academic entity, the most important product of our laboratory is our students, post doctoral fellows and visiting scholars. Our students will all develop unique expertise in sensors, NDT, and structural health monitoring by the time of their graduation.
