Research Interests: My research interest is in the dynamic field of material science, with a focus on hybrid materials, perovskites, semiconducting, and metallic nanomaterials. These materials hold immense potential for transforming various industries, including optoelectronics (such as LEDs and phosphors), photovoltaics (such as absorbers for solar cells), sensing technologies, and catalysis.
The core of the work involves design and synthesis of various functional materials and investigation into their structure-property relationships. This knowledge would be applied towards tuning their properties and enhancing their efficiency in various applications.
