Research Interests

My research interests lie in the development of nanostructured optoelectronic devices and gas sensors. By harnessing the potential of nanomaterials, I aim to fabricate cutting-edge devices that exhibit improved performance, efficiency, and adaptability. I am dedicated to advancing technology in these fields, seeking applications that span from high-efficiency solar cells and photonics to highly sensitive gas sensors for environmental monitoring and healthcare diagnostics. Through the synergy of these technologies, I aspire to play a pivotal role in addressing critical issues spanning energy, environment, and health.
