My research focuses on functional oxides for electronic applications, from materials design to applications. Materials include new eco-friendly oxide-based ferroelectric polycrystals for energy harvesting and storage, photo ferroelectrics for a new generation of photo actuators, and multiferroic heterostructures for light-controlled devices. High-energy X-ray (Synchrotron) characterization is also at the core of my research. Other interests include relaxor ferroelectrics, ferroelectric domain dynamics, grain size effect on functional properties of ferroelectric materials, advanced characterization of dielectric and piezoelectric properties, and ultrasonic devices based on piezoelectric technology.
