Dr. Roy’s research interests broadly include engineering novel functional materials to improve electronics for Internet-of-things, and development of energy-efficient devices for electronics and sensors. She is interested in developing electronic and optoelectronic devices with two-dimensional materials for low-power computing. Another aspect of her research dwells with wide bandgap semiconductors for high-power electronic applications. She is keen on studying the reliability of different materials systems and semiconductor devices.
