Advanced devices for Energy Harvesting in Infrastructures
My current research focuses at SMART LAB at Purdue University on developing a novel flexible piezoelectric nanogenerator to harvest the existing mechanical vibration of the infrastructures such as bridges, buildings, and pavements. The stored (harvested) energy can be further used as a sustainable and green power source for wireless sensors, light, signs, etc. At Purdue University, I have fabricated a flexible energy harvester, in which the frequency can be tuned based on the available frequency range in host structure. This device shows great promise to be used in civil infrastructure because of its high flexibility, high strain capacity, low-cost and high efficiency.

Advanced Sensing techniques
My current interest focuses at SMART LAB at Purdue University on developing a piezoelectric-based sensor for sensing, material characterization and health monitoring of civil infrastructures. The current nondestructive testing methods are inefficient, costly and difficult to implement into the structures for real-time measurement. I have developed a piezoelectric-based sensor which can be easily applied to the structures. The polymer piezoelectric-based sensor can be either embedded in the structures or bonded as a patch on the surface of the host structures. The developed sensor can be used not only for detection of cracks but also for physical characterization of cementitious materials.

Sustainable materials for infrastructures
My work in this area includes: 1) enhancing the service life of the concrete structures mainly by incorporating advanced nanomaterials. 2) development of an Eco-efficient ultra-high performance concrete 3) development the durable and damage resistant cementitious materials. During my research at the technical university of Lisbon, I designed and characterized an ultra-high durability concrete (UHDC) which can be implemented as an everlasting cover layer in precast concrete members as well as in the rehabilitation of existing ones to extend the service life. This work proposed a new generation of nanocomposite concrete in which the service life of the structure can be extended more 100 years.
