We investigate novel advanced materials and device photophysics through advanced spectroscopy as a powerful tool to understand their characteristics at different length and time scales, unveil the origin of instability, and maximize the output of advanced energy devices. We are dedicated to exploiting our research for the development of actual products, thereby bridging the gap between fundamental science and technology commercialization. Through active industrial collaborations, we facilitate technology transfer into multiple emerging markets, including green catalysts, photovoltaics, the Internet of Things (IoT), and consumer electronics. Our research activities encompass three main multidisciplinary themes, with most projects in the group falling within one or several of these categories. These sub-sections serve as a valuable resource for prospective applicants seeking a comprehensive understanding of the group's activities.
